Sony's going to steal away the backwards compatibility domination yet again, as it has done in the past. We're talking physically compatible with older titles. Pop in a PSX disc and it'll boot up nicely (although, after playing with supposedly "far superior HD graphics," it'll be hard to look at a PS1 title and be satisfied... :P). The Rev will play GameCube discs, sure, but that's about it as far as just popping in a game from the previous generation. The 360... well, it could have handled backwards compatibility much better.

I mean, sure, you can access games from previous Nintendo systems on the Rev, but you can take an old NES cartridge and put it into the disc slot of the Rev. You'll have to pay for a copy of the game (which is probably enhanced) and have it downloaded to internal memory. 17R3W's right on the mark here with this observation.
