The problem with the original Kinect is that given the fact that it was an accessory it had a more limited audience, so games wouldn't be THAT successful unless they won the lottery and it became crazy viral. XONE Kinect is bundled with the console so any game can include Kinect features whether they are the main control (Fruit Ninja) or have just a small yet maybe useful feature (Shouting things to psychopaths in Dead Rising 3) and not having to worry about the fact that they're dealing with a smaller audience like in X360.
At least, that's how I see it. Feel free to correct me if I'm wrong.
