I answered this question when you asked it in the waiting room. I still have this with my vin in source...guessing it means the VIN isn't on the actual manage page yet. Like others have said, your VIN is coming, relax.
It means just that. You can even have a VIN assigned, but until the car is built and scheduled for delivery, it won't be "revealed". I got my VIN on 11/20, and it didn't appear on my acct. page until the following week.
