Yes! So it was quite game-changing since cars made before the hardware shift had no chance of ever evolving with just software or a straight forward MCU upgrade.
It was also a huge deal to me, personally, because unlike the vast majority of Tesla owners at the time, I didn't have money falling out of my ears. I stretched and twisted and cut and took an 8 year loan to have the privilege of ordering a Model S. So if I would have gotten a car that was immediately obsolete, it would have hurt. A lot.
Also of note: Autopilot was literally announced/discussed/unveiled at an event in October of that year. I was already in the middle of my wait so Tesla allowed me to change my order. I think I had ordered something called the "tech package" plus fog lights ($500 option.) They allowed me to swap to AP, which was $500 more than "tech" but fog lights had then become standard so it was a wash.
