MGS4 = optimized for PS3. MGS:R = optimized with multiplatform in mind.
And MGS4 not being possible on the 360 wasn't from a purely graphical standpoint. I think Gears 2 looked better than MGS4, so it's not the graphics department. It was the AI, the audio, MGO, and of course the coding that made it not possible on the 360.
