24 million units of the Kinect sensor had been shipped (shipped does not mean the same as sold) as of January 2012.
Best case scenario, as of January 2012, is that 1/3rd of the target audience has Kinect. That means 60% (or more) of Xbox 360 console owners do not own a Kinect. That's a pretty big difference when it comes to programming games. Do you make the game so that more users can play it, or do you make it so that a smaller group can play it with motion controls?
