This is what we got at the Mission Viejo store.
4GB Kinect Bundle - $200 (gift)
2x Disneyland Adventures - $15 (one a gift and one for us)
Dance Central 2 - $15 (gift)
Assassin's Creed: Revelations - $28 (for us)
Total was about $250 after tax and 15% off discount. We consider the Christmas shopping practically done. The Xbox 360 is going to be a gift for my girlfriend's whole family.
The store wasn't mobbed and there were plenty of copies/units left over of anything you could possibly want. We waited 20 minutes but there was no reason to. Plenty of people had stacks of three Xbox's.
