Quick update, my app no longer shows any type of estimated delivery date. It no longer says "Estimated Delivery" anywhere at all. My account on the website still has an estimated delivery date of "Dec 2022" but it is 6:30pm on Dec 31st and I still have not been assigned a VIN (not even in the Page Source). On the 24th my SA told me that my original delivery date is the most accurate but has since gone on to make sure to let me know the estimated date is, in fact, only an estimate. There has been no new inventory Model 3's or Y's in my area since the 18th either.
It looks like I won't be able to take advantage of the $7500 + 10k Super Charger miles.
