0% chance.
Why would I buy a game like Killzone 3 when the market is going to be flooded by better FPS games likes Halo Reach, Black Ops, Crysis 2, Medal of Honor, and in 2011 Gears of War 3?
Most anticipated games of 2011:
Uncharted 3,Legend of Zelda: Skyward Sword, Rocksmith
Modern Warfare 3, Super Mario 3D
