Of the currently on the market games I think the bases have been covered above. I don't see the other 13(?) games cracking 1 million. Your Shape and Kinectimals will probably take a while to get there.
Plenty more Kinect games to come, meanding plenty more million sellers.
But 15 *million sellers will take a pretty long time to get there. Gotta figure that given about 15% of 360 titles crack 1 million (109/731 -which is the best million seller % of any current system excl PS2) that the proportions for Kinect will be roughly similar (if anything lower). So for 15 games to sell 1 million it means there will need to be ~100 Kinect games released. For 30 games there will need to be ~200 Kinect games on market.
What's the Kinect game release schedule? How long will it take to release 100 games?
