The controller is, indeed, unorthodox and I don't think it'll feel the same playing a game such as Super Smash Bros., Legend of Zelda, etc.

It seems like a new and good idea and even though I'm a little skeptical, I wouldn't mind using it.

I'm just glad that the controller is going to have added on peripherals so in case one doesn't like the normal remote and nunchaku-esque controller. Rumors speculate peripherals from ordinary Gamecube controllers (Dreamcast style, with the remote put into the middle) to a shotgun in which you slide in the remote at the end.
