I wonder if that applies if you live in Texas... If you live in Texas, what are the odds of getting an MIT MY?If they're gonna put 4680's onto any Model Y's, it'll start with their Performance trim.
I'm in the Chicagoland area and delayed my Model Y Performance delivery to at least May of 2022 next year. With me being east of the Mississippi, I'm hoping I'll get the new Y's from Austin as Tesla's plan for Austin is anything east of the Mississippi comes from Austin, while anything west of the Mississippi comes from Fremont.
About 7 months ago I was debating this same thing, holding out for the 4680's. It seemed like they were always just over the horizon so to speak. I was very tempted to hold out but following the sage advice of someone here, I went ahead and bought put in my order then. Given how much the price went up since then it was a massive saving and a pretty rare time where the car has appreciated in value.
Given the incredibly long lead times, it makes it pretty difficult to determine what you might actually get. More importantly Tesla may say the new 4680's are an all-new model and your reservation may not directly transfer. That would allow them to blow out all the lower-priced reservations where people are "speculating" that they'll get the latest and greatest at the old price.
Now they may be nice and let you transfer your old MYP reservation to the MYP+ version but there are no guarantees. Nothing also says their current approach of letting you delay your delivery when you receive VIN will remain in place.
With enough demand, they may care even less than they currently do about their customers. If you don't want to take your order when it arrives, and they can replace you with someone paying $5-10k more, there will be a lot of incentive to bump and dump you. Given the fact they bumped the ordering fee up from $100 earlier probably indicated some people may be gaming the system a bit. I wouldn't be surprised if they bump it again given the demand. It will also help see how firm that demand really is as well.
