Nothing. Systems live and die by their software. Kinect has done very poorly with software. Kinect also failed to attract new gamers. It appeals only to current owners, and namely as a tech device. It hasn't shown it's potential as a gaming device.
There is no threat from Kinect. All of it's software is ripe off of Nintendo (which is why the software isn't strong on it). So long as Nintendo makes good games and ideas that the others thought up, they'll be fine.
There isn't a future for Kinect because there is no software.
