kinect will sell well, it will sell around 5-10 million max and thats pushing it
xbox has 45 million shipped units but alot of people have bought more than one console (RROD) so lets say there is 30 million 360 users. There is No way the Kinect can sell 20 million units as thats really pushing it, thats around 2/3 of the user base, not everyone has a wii fit board for the Wii and everyone doesn't have a guitar hero controller for the PS3/360/Wii as well. So the market is small so its hard for Activison and Ubisoft and EA to bring out High quality games if the market is too small. If the kinect was 50-100 dollars with a few good games then you might get a larger sales.
Of Course That's Just My Opinion, I Could Be Wrong
