Who cares how it's connected, as long everything's integrated I'm happy.
As for the kinect, the simple fact that every Xbox one comes with one will open up tons of new avenues for developers to add features in their games. The stuff that some of these companies will come up with to use the kinect for will revolutionize gaming. Just give it a year or two to see what the kinect enables the Xbox to do. It's an amazing piece of technology and I can't understand why you wouldn't want it.
