Only valve has the balls to try some innovation like this. Not sure how it will work, but it could be brilliant, or fail. I wouldn't count valve out. Typical people judging too quickly.

Sorry, but why would a console company make a controller like this? Racing games, platformers, fighting games, adventure games and rpg's don't get anything from such a design. It's MAYBE good for FPS and RTS but then, mouse and keyboard are still better.

Have you used it? Fighting games are not exactly big nowadays.
