Honestly, this isn't new information either. They should have know their actual allocation number for a couple of months now. Not sure why you are just now getting this information. Also, the dealer should (theoretically) understand that the initial number was just an estimate. I don't think...
You are fine. I ordered BL originally and changed to a WT. The website never did update. I received the email with my VIN and it had all the correct details included.
