I think Move will ultimately be more successful due to the greater variety of games that can be played on it. Kinect lacks some sort of direct response device and that limits the commands you can give to the game. However, I think both will face the peripheral problem. Move is attached to what is already the most expensive console and will require the purchase of more controllers that are only useful with Move games. Not only that, the price goes up if you want to play group games. Kinect only requires one device but what it can do is more limited. Neat, but limited. Direct input from pressing buttons allows more options for the game and combined with the motion tracking, a more dynamic experience. Just motion controls by themselves mean that the developer will stick to simple and easy to express gestures.
I give this thread a 9.6.
Thank god for the disable signatures option.
