I feel like a lot of people are lowballing LBP2, the first game was release during the holiday which is why it has such a low drop off but LBP2 should have plenty of leg as LBP1 is still selling and still a popular budget title. I expect it to reach 4 million at least.
Anyways for your list:
LittleBigPlanet2 5 million
Killzone 3 2.5 million
Yakuza 4 800k <--- remember that this game is already about 590k due to Japan sale.
Playstation Move Heroes - 800k
MotorStorm Apocalypse - 1.3 million
Socom 4 - 2 million
Infamous 2 - 3 million
Resistance 3 - 3 million
Uncharted 3 - 5.5 million
Sorcery - 1 million
The Last Guardian - 2.5 million
Ratchet & Clank: All 4 One - 1.2 million
Twisted Metal - 2.2 million
Game that you missed:
Ar Tonelico Qoga: Knell of Ar Ciel - lol
Hyperdimension Neptunia - lol
Tale of Grace F - 500k
Disgaea 4 - 400k
MLB 11: The Show - 650k (its the most consistant game I've ever seen! the same hardcore baseball fan must get this every year!)
