the trailer is really impressive stuff, and i believe it is the real deal. but who cares. the game isn't going to look like that. remember back to all of the other MGS trailers. they all looked amazing, and were in fact done on the real PS/PS2 hardware. actual gameplay didn't come close because you can't play a game with fixed cameras. this will be just like before. the difference with MS is that they have been showing almost entirely in-game screens and demos. there hasn't been one developer to make a comparable length, non-playable demo for the 360. it really would have helped MS if they had.
