Well I expect a stealth release of both. There is a LOT of chatter about new 90's being secret 100's already, due to a mysterious power output increase. Also the 1.0 AP hardware was stealth released so it's reasonable to think they would do it again. They might really not know the final config. New mirror housings are already reflecting 2 camera spots, but only populated with one camera. My feeling is they may start sticking in the sensors they know they will eventually need as soon as they can. So maybe in Sept they start making cars with new radar sensors, extra cameras and say nothing because the SW isn't done and they aren't totally sure they have the HW right.
What is puzzling with the theory that 90 is actually software limited 100 is why would not go public with it? I get that Osborning possible only among the engaged and itching, but that population could easily be 10% or more. These 10% could be the difference between 2000 cars/week and 2200 they really need to bolster their cash position and appearance of being in control of near term planning.
Do they still working on validation before announcing the new battery size? Are there any other complications? It looks like time is running out for this upgrade to have meaningful contribution to the top and bottom line in 2016.
