The PS3 has enough exclusives since the MK9 has Kratos, Deadspace 2 has a new extar mode IIRC, Batman: AA has the joker you can play as.
The PS3 other great game exclusives like Killzone 2 & 3, Disgaea 3: Absence of Justice, MGS4, Demon Souls, Final Fantasy Versus XIII, Heavy Rain, MotorStorm, inFamous, Disgaea 4, Resistance series, Yakuza 3 & 4, God of War 3, White Knight Chronicles, LittleBigPlanet, and the Uncharted series.
The 360 has none of those games, and 360 users should stop bitching.
