While I think
@calisnow's conclusion could play out, I don't think it's anywhere near the confidence level where I'd change my timing on a vehicle purchase. Model 3 won't be built and sold until 2017 (to employees) and sometime in 2018 for the general public. If it's anything like the X rollout, there will be token 2017 deliveries and a slow ramp. They don't have to release AP 2.0 in the S and X until
that time, assuming that part 2 truly shows a tremendous gain in that particular tech. So
assuming that we see a big improvement in the part 2 reveal, and that's an assumption based solely on the words "the obvious thing," S and X sales will continue with the current suite because they can just say "this hardware will be available in the Model 3s that roll off the line."
I think
@ecarfan's response wasn't generic, it was the more responsible of the two.
Connecting some widely scattered dots to draw a picture
is a fun and valuable exercise, but
to imply others should make financial and life decisions based on those is probably not the best advice.
