What If Modern Warfare 2 Was A PlayStation 3 Exclusive?

PSXextreme writes: You know, I think it's a question worth asking. In the very recent past, journalists and gamers alike have seen what developers dedicated to the PlayStation 3 can do if they focus all their efforts on producing a game specifically for Sony's console. Due to this, the other part of the debate centers on the following question: could making a game for both consoles be holding the PS3 back? Naughty Dog has already said Uncharted 2: Among Thieves would have to be a completely different game on the 360 as they utilized much of the special Cell Processor. Guerrilla had similar things to say concerning Killzone 2 and those who have played both often agree that nothing on the 360 can compare to either of those two titles.
