This doesn't seem to be much of a surprise but it seems women (or men if you like to dress this way) 
won't be able to wear long skirts to use 
Kinect. Seeing as how the camera tracks movements and such in various points, you would have to figure some clothing types would interfere with it. Again, not much of a surprise in my opinion and not that big of a deal compared to other things 
Kinect-wise such as the pricing.
Those that want to pre-order 
Kinect in a bundle 
can do so through Wal-mart right now.
