I don't know, but VG Leaks think its not a focus and they've had a modicum of accuracy.Do you honestly believe Kinect won't be a focus? I don't mean at Gamescom, I mean as a whole. Highly unlikely.
I mean it depends on what you mean by focus. Do you mean the delusional anti-Kinect poster idea of focus where Kinect has been shoehorned into every major first party release since its release and we now live in a world where there are no controller based games left on Xbox, or do you mean, do I think there will be Kinect-only Xbox games? The latter is, I think, certainly true but I would hesitate to call that a 'focus' on Kinect.
