It's a toss-up between PS3 and X360, but I think I prefer the ol' Playstation. Metal Gear Solid, Grand Theft Auto (not 1 year later...). However, X360 will correct one of the only things I didn't like about the old X-Box, that is the white and black buttons on the controller. A lot of sports games require you to press the white or black buttons while pressing something else, which is physically impossible unless we had 2 thumbs on each hand...

And a tip of the hat to Nintendo. While they certainly aren't as big as they used to be, at least they're taking the opportunity to try something different. It remains to be seen whether it'll work. I gotta admit, playing Metroid while pointing the controller at the screen and shoting things sounds like fun!
