I'm pretty sure anyone who already ordered will get their $35K car, as otherwise people will be suing. Anyone ordering now, you snooze, you lose.
Yes, that's how I read it. As someone who hung in there for over a year, waiting for my 2013 Model S 40, I was amply rewarded with a 60kwh battery (software limited) and a great car at a great price. Resale value was amazingly good. Those who placed their orders for SR and hung in their will be similarly rewarded. They will be driving true $35,000 Tesla Model 3s (plus options), but with the better interior, electric seats, seat heaters, etc.
The SR will have to be priced at $37,000 with autopilot because if it was $35,000 it would draw too many orders away from the SR+.
I concur with Neroden that Tesla has likely had too much downtime changing the production line to accommodate variants of the Model 3. It's time to reduce the variations and allow the Model 3 line to produce higher quantities of vehicles.
