Gamers who consider their core hard have always thought of Kinect as just some gimmick Wii-successor that they'd never use because true gamers use analog sticks or fight pads or morse code or something. And maybe the first Kinect was like that. The Kinect 2 on Xbox One? Completely different. It's truly an extension of the controller without the constraints of a controller.
We already know the Kinect 2 is ridiculously powerful enough to see your heart beat just by looking at you and that its innards are stupendously smart. But the point of bundling Kinect with every single Xbox One ever isn't to force you to host Dance Central parties or make you teach Skype to Grandma, it's so that Microsoft can make a better controller without changing its controller (without changing it too much, I should say. The new Xbox One controller is tickle me sweet).
