My prediction for the next 3 weeks and three days.
Week 1 (Dec 8 - 14): California (Oct Orders) will all finally get VINs while Upper West Coast, East Coast and Central Coast continue to take VINs & deliveries (especially those who placed orders in Nov and Dec). Backlog for non California should
probably be lower at this point. (I hope)
Week 2 (Dec 15 - 21): Flood gates open! California (Oct Orders) will take deliveries, California (Nov Orders) will be assigned VINs, all other regions continue to prosper as they have been.
Week 3 (Dec 22 - 28): California (Nov Orders) Take Deliveries, California (Dec Orders prior to the 8th) will be assigned VINs.
Weekish 4 (Dec 29 - 31): California (Dec Orders) Take Deliveries and whatever remaining
Just wishful thinking, but who wants to start placing bets step right up!
