I've made a list of the various disclosures to date surrounding the June 20th announcements. (This was moved from nested deep in another thread).
Please reply on this thread if you have any other potential sources - I'll add it here to the top-level post to have in one place. It doesn't necessarily have to be directly related - it can be something that is regarding one of the prevaling theories for the announcement.
Direct disclosures regarding announcement:
Elon, Twitter - Apr 2:
Today's Tesla announcement is actually the 2nd in a 5 part trilogy (love Douglas Adams)
https://twitter.com/elonmusk/status/319119973366784002
Elon v. Betty Liu, Bloomberg - Apr 2:
And then there's a 3rd announcement that I won't quite talk about, but I think is pretty cool - except to say that if you're driving a Model S, it's right under your nose.
http://www.youtube.com/watch?v=LS2BCL6SWYI - 8:49 min
[3rd in context here is 3rd since the Lease announcement. So 5th overall]
Elon, Twitter - May 9:
elonmusk: There is a way for the Tesla Model S to be recharged throughout the country faster than you could fill a gas tank.
realbhuwan: @elonmusk yeah, we're waiting for superchargers :wink:
pjhornak: @realbhuwan @elonmusk hint that's not a supercharger
realbhuwan: @PJHORNAK doubt it is anything else.
elonmusk: @realbhuwan Don't forget the mystery announcement. Part 5 of the trilogy.
pratik_shah: @elonmusk only in US or across the globe?
elonmusk: @pratik_shah worldwide [<---- this has since been deleted]

Elon, Supercharger Announcement, May 29
It is sort'a a concentrated series of announcements, and I did say it was like "Five Part Trilogy". Athough, then we had intermission. And then the [billions of buy and see and made up an area?] that wasn't part of that plan. That was sort'a unexpected intermission. But after the Five Part Trilogy, named in honor of Douglas Adams, we're going to be queiet for a while so you should expect that after this announcement, there is one more on June 20th, which I think is going to be pretty exciting. That will be an in-person thing, and then we won't have anything to say for a while.

Elon, Stockholders meeting 6/4/2013
Q: You recently tweeted about that it may take less time charging a Model S would take actually less time than filling a tank of gas. Is the recent announcement that it is 20 minutes. Is that it now?
Elon: No. That is not it. That is not it. I would say, you should... I mentioned there will be an announcement on June 20th, in fact, not an announcement, but a demonstration. Live demonstration.

Associated 'Prevailing Theory' disclosures:
So far the prevailing theories I'm tracking are:
2012 shareholder meeting
Q: I think last year you mentioned how there was a swap-out of the battery with the Model S and that could be done, I've been telling people, in under a minute potentially. So could comment about that and whether that looks like something that still has potential and when that might happen?
Elon: In terms of the Model S, I intentionally architected the Model S to have a battery pack in the floor pan that can be swapped out in under a minute. I think we're going to show something interesting in that regard. (Elon smiles, audience chuckles.) I've got to keep a few cards in the vest. But I think there will be something exciting to see in that regard.
http://www.teslamotors.com/2012shareholdermeeting 41:50
SEC 10-Q - May 10th
Other factors that may influence the adoption of alternative fuel vehicles, and specifically electric vehicles, include:
* our capability to rapidly swap out the Model S battery pack and the development of specialized public facilities to perform such swapping, which do not currently exist but which we plan to introduce in the near future;

Javier Verdura, Core77 - May 28:
Charging technology is only going to improve with time. Charging times will decrease significantly and range will increase accordingly. In the very near future, the argument that internal combustion automobiles are more convenient than electric vehicles will be a moot point. You will be able to arrive at a charging station with an empty battery and drive off with a full charge faster than you can fill up a gas tank.
http://www.core77.com/blog/announcem...tors_24947.asp
[The tie in is the "faster than you can fill up a gas tank" - wording that Elon used on May 9th]
Elon, Supercharger Announcement, May 29 on Grid Storage
Q: Can you explain how the Solar works for the stations that do have solar?
The general principle is that we want to generate more energy from the sun over the cause of the year than is used by Model S's that
recharge at the station. The recharing tends to be concentrated during pretty obvious times, like on a Friday afternoon and evening and on
a Sunday afternoon and evening, cause people are going somewhere for the weekend or on holidays days - that kind of thing. Whereas it sees
relatively low usage during the week. The solar panels are generating energy throughout the course of the week, and it cummulatively adds
up to more than the energy that the car consumes.
And I was thinking of saving this bit of information for a future announcement, but you do make a good point, we've kind'a had too much
news. So I'll just pack it in here, which is that we actually have grid storage going on at sort'a our SuperCharging stations. So we got
stationary battery packs that take in energy through the week from the Solar Panels and - the Solar Panels actually charge the battery
pack and then that stationary battery pack charges Model S's, and so it's actually capable of going completely off grid. And this is
something we expect to probably roll out to all the SuperCharging stations, and I think it's something that's sort'a fairly cool. These
stations will then operate even if the entire national grid goes down.
http://ir.teslamotors.com/releasedet...leaseID=767983
https://www.dropbox.com/sh/yozowduql4vggzq/rDQXdo7Hqm 22:23
Long term I expect all SuperCharger locations to have Solar and Grid Storage. It's kind'a just a matter of time. In order for us to deploy
the SuperCharger locations very rapidly we have to start of with them not having Solar and then backfill the Solar over time. The
completion of the Solar is going to lag the SuperCharger network by probably 12 to 18 months and then Grid Storage is another 6 to 12
months after that, I would imagine, but these are just rough estimates.
David Baker: So how many of the Grid Storage units do you have out there, and how big are they?
Elon: We've got 2 in operation right now. They are pretty sizable. Half a Megawatt Hour, and they're capable of putting out a Megawatt if need
be.

We've got 2 in operation right now. They are pretty sizable. Half a Megawatt Hour, and they're capable of putting out a Megawatt if need be.
Q: Where are they located?
Actually, I'd rather not say where they are located, because I'd rather not have people go and fudging around with them. I'll tell you they're in California - there's probably only a limited number of stations. And we're actually doing this in partnership with the utlities, btw, so. The grid storage is considered a helpful thing to the utilities cause it allows them to use that pack as a grid buffer. The utilities always have a challenge of dealing with too much or too little power generation at a time, so we're able to provide that buffering capability which they like.

Elon, Supercharger Announcement, May 29 on Battery Swapping
Kevin: With 20 minute charges, do you see any roll in the future for Battery switching?
Elon: Well, today is about charging. I should say that I'm a big fan of optionality and I talked about battery pack swap for a long time, since
really the beginning of Tesla. And I don't think pack swap is a particularly brilliant idea. I mean, obviously we swap battery packs in
cellphones and laptops, so it's pretty obvious that such a thing can be done, at least at a small scale. The question would be could you
do it with something much larger, and then, how convenient would it be, and what are the economics like. Maybe we'll have something to say
about that in the future.

Elon, Supercharger Announcement, May 29 on Partnering:
Conceivably if we were to do a partnership with a major manufacturer that were interested in the SuperCharging system and are willing to use the same basic architecture, then it could be used by more than just Tesla. We're not closed to that idea. We're not trying to create some closed system as some sort of strategy or something like that. It's just that we need to solve the problem of long distance travel and we can't wait for others to agree with our strategy. If we wait for some sort of concensus, it's going to take too long. So we just need to keep going and then other manufacturers can either copy us or join us.

Elon, Jim Cramer interview, May 31:
@retrowallstt: Given the downtime (20+min) at recharging stations, is there any plan to create a "customer experience" during that time?
Elon: Well, we're aiming to keep improving the charge speed, and then we got some other ideas for minimizing people's time at charge stations. But ["that's not it..."?? Maybe. What is the exact wording here? I can't decipher.]. But yeah, I think... we'll try and come up with some entertaining things over time. I mean Right now we're just really focused on expanding the Tesla stations around the country and making sure that you have the freedom to travel anywhere you want, anytime you want.
