I was at Walmart in Orange, California today and I say an ad advertising a Gears of War 3 beanie upon purchase of Gears of War 3 at midnight. It looks pretty neat.
Definitely:
Gears of War 3 (epic edition!)
Battlefield 3
Halo anniversary
From Dust (xbla)
Rage
Dead Rising: Off the Record
Maybe:
MW3
Batman Arkham City
