GTA4 360 exclusive DLC good/bad?

[Omega_Phazon_Pirate.]

"Gears2 dev said the game pushes the 360 to limit graphically, no such thing has been said for a PS3 game."

I could be wrong here, but didn't MGS4 do that? Or push most of it? Someone correct me please, because I am curious on this.

Also, didn't Uncharted only push like 20% of what the PS3 is capable of?
