The future generations of kinect will bring astonishing changes to the world of gaming. You assume the new capabilities will be used for "malicious" means which is possible but that's a bad way to judge some technology. That's like saying the next Gen Intel CPUs will be 2x faster so people will use it to spam twice as much or hack passwords twice as fast.
The fact of the matter is Kinect will continue to shape the future of gaming. The hardware is just not good enough for hard core gamers currently. Once that barrier is gone I think it can create a much more immersive gaming experience that would benefit all gamers.
