I must admit I am suprised by the continued strength in the Kinect – one must assume these June XBox sales numbers are being driven by the Kinect.

There still are no good games for the Kinect for hard core gamers, so it must be driving a broadening of the appeal of XBOX to non-gamers. Microsoft is planning to roll out even more titles with Kinect support, but I contend the real future of Kinect is not with traditional gamers. The biggest market in games is first person shooters, and Kinects concept doesnt seem like it would translate well with first person shooters where the player is often having to look left, right and behind.
I still contend the Kinect will find its best market outside of gaming. Microsoft did not foresee the huge interest in people modifying the Kinect for other uses (see http://kinect.dashhacks.com/). By popular demand, Microsoft just released an SDK to allow programmers to write programs for the Kinect for the PC.
My guess is the Kinect will find a bigger market outside the gaming world than within it.
