to put it simply, no. you aren't going to see ps3 or revolution games running on the 360. the only way this would be possible would be if there was an emulator to port over, and this isn't going to happen. its about as likely as seeing a ps2 or gc emu on the xbox any time soon. also,even if they all have PowerrPC's (which they don't), the ps3's cell cpu (not even very similar to a powerPC from what i understand) is nothing like the x360's tricore PowerPC processor. also, don't forget that the graphics cards will all be differant.
