Dead or Alive 4 didnt sell all that well exclusive to the 360. Then again...it is a crappy fighter. FPS games do sell on the PS3, just slower than Microsoft.
Exclusives I expect sony to add to the million sellers list this year are Last of Us, God of War IV, Starhawk, Dust 514.
Halo 4, Fable Journey, Star Wars Kinect, Dance Central 3, Kinect Sports 3 ect.
