I realize that your stock portfolio has forced the creation of a severe reality distortion field around yourself but you really should step outside and join us here in the real world sometime.
Actually if you look at my posts in this thread I only posted facts. First a very recent quote from Elon Musk. Then refuting your claim that Tesla has never hit a stated date.
My personal guess is Gen3 will come out sometime in 2017, as Tesla still appears to be shooting for a late 2016 or early 2017 timeline, which is really only 2 1/2 years away. But I'm giving 6-12 months for delays.
When people say there's no chance Gen3 will come out in 2017, it doesn't add up. Tesla's design team is done with Model X so they're working on Gen3 full-time. Also many of their engineers are pretty much done with Model X so they are also starting to focus in Gen3. The reason why Elon is saying Gen3 is about 2 1/2 years away is because they're actively working on Gen3 and they have a timeline. Can they timeline be delayed? Sure. But is the timeline impossible to fulfill? No.
Many people look at the Model X delay as proof that Tesla can't keep their stated deadlines. I disagree. Model X was delayed not because they couldn't keep their deadline. They could have released the Model X earlier if they wanted to but it makes strategic sense for them to push back Model X as they're still ramping up Model S because demand is more than double they anticipated.
Tesla anticipated Model S global demand to be 20k units a year and Model X demand to be 15k units. What many don't realize is the Model S demand blew away Tesla's own internal expectations, and that's why they were so production-constrained. Their agreement with Panasonic was made expecting 20k units of Model S a year.
So the Model X wasn't an execution error, it was a strategic move to push it out. Sure, there was a slight delay from end of 2014 to early 2015, but Tesla did that because they could (still ramping Model S) and they can afford to make the Model X better.
When you look at the Model S, in early 2010 Tesla said they'd start production in summer 2012, about 2 1/2 years from then. Most people scoffed them and said it was impossible. Sure earlier in 2009 they were hoping for a late 2011 production start, but Elon said his first hard promise for a Model S production start was when he said summer 2012 (back in early 2010), and he said he did his best to keep that date because it was a hard promise.
Now with Gen3, Elon hasn't made any hard promises. Late-2016 or early-2017 is an internal goal, so yes this date could be pushed back. But it's entirely possible that Tesla could start releasing limited number by that time (ie, founders cars).
Another factor is that while Tesla does miss many hoped for dates (I have no problem acknowledging that), if you look at the bigger picture Tesla is growing much faster than most anyone expected a couple years ago. Look at the number of stores and service centers. Look at the number of superchargers. Tesla IS moving fast, especially with their big initiatives. And Gen3 is going to be their biggest initiative yet. This is different than the Roadster "special something" for owners, which kind of got pushed back since it really is a low priority for Tesla (though Elon backtracked and said they'd do it this year because they said they would).
Another factor is Gen3 timeline is a huge set of moving parts. Gigafactory needs to start coming online at that time. They need to prep tooling, testing, etc. This is an enormous task and the entire company will be focused on this as their top priority in the next few years. I don't see this slipping more than 6 months from their currently stated goals, mainly because their target is only 2.5-3 years away and they are already working on Gen3.
Finally, I personally think that Gen3 will start off with smaller production and slowly ramp to volume production. Initially, it will likely start with signature cars (ie, 10k?) over the first 6 months as they work out the kinks of production. Then they'll slowly ramp from there. So I don't expect volume production to start until about a year or so after initial production, probably in 2018.
But I'm fully expecting the first signature Gen3 to be rolling off the line in 2017. Too much of Tesla's future depends on it for them to delay it beyond that.
