I want the revolution because it's going to be something new. Remember the jump from SNES to PS? That was big because of the jump from 2D to 3D. It's the same with Current Gen to Revolution. It's not just prettier graphics, it's a whole new level of gameplay. It's going to do new stuff to the industry...stuff that we haven't even imagined yet. 360 and PS3 may have pretty graphics, but gameplay wise, they aren't going to be able to do as much more new stuff as the revolution can.
BTW, having played a 360, I can say that the controller is very comfortable, and that it is a good console - I don't now much on the game front, but Fight Night is fun, and supposedly, GRAW and Oblivion are too.
