a couple of thoughts on AP2.0:
1) I agree that 2.0 will be revealed for S/X sometime this year because per Elon new tech will always appear first in S/X, so the reveal must occur prior to M3 reveal part 2.
2) Unlike the AP1.0 reveal, which occurred before the sw was ready (how many months after the 1.0 reveal before sw was available?), I would expect something similar for 2.0 EXCEPT that I think that when they start shipping 2.0 hw it's going have to work at least as well as 1.0 (not sure customers would go for buying a car with less functionality than the prev generation).
3) If you buy my assertion in 2) that seems a lot harder than jus shipping cars with new hw. They have to have a lot of functionality in there from the get go, and with new sensor suite and new computing platform to boot.
So I'm a bit skeptical that AP 2.0 is right around the corner. Curious to hear other's ideas about the rollout might go tho.
