I'm going with Kinect for sheer boldness. There is a chance Microsoft could hit it big, if they do it right, and it has implications the gaming industry has never seen before. Move to me is really just a port of an existing product, so as great as it could be, it's going to be limited in what it can do.
Gotta be honest with you shayd,I feel the same way about Kinect as far as pure game play goes,but make no mistake,I'm not a fan of the Move either.
