Kinect 2 - What it should have & what is shouldn't?

We all love Kinect and the countless possibilities it has opened for engineers all over the world. When Kinect 2 will arrive, we have no idea; but it sure has high hopes attached.
Till Microsoft reveals what Kinect 2 would be like, let us discuss what we are expecting from it here.
Firstly, I think it should have substantial improvement over the current hardware & dedicated hardware processing. Along with better voice recognition, I think it would be great to have a four player tracking.

Spill out your beans. Since, this is just an expectations list -> blurt out any imaginable things that you can here. 😀
