Hmmm for me there are plenty of exclusive games I'm looking forward to on both consoles this year.
PS3 Exclusives I want are -
Killzone 2 (Hope it is as good as its being made out)
Uncharted 2 (anything like the first I will love it)
Heavy Rain (anything like farenheit then again amazing)
GT5 (really enjoyed prologue so full game should be amazing if they ever get it out lol)
God Of War 3 (Never played any of the others but looks good)
Infamous (Again looks brilliant but will have to wait and see)
MAG (Has huge potential)
Boarderlands (not much info but hoping its good lol)
Xbox 360 Exclusives I want are -
Alan Wake (Been waiting for this game for so long. Looks amazing)
Alpha Protocol (Again looks like it could be good)
Theres probably others but I cant think of them from the top of my head. I sure I have probably missed some great RPG's well I hope so anyway

Resident Evil 5
FF13
Prototype
Fear 2
Velvet Assassin
I Am Alive
Fightnight Round 4
Street Fighter 4
