you do realize that kinect just came out like a month ago. Its not going to have 100 games already, you should really consider this like a console launch when games aren't many in numbers give a few months before you go criticizing it on its current software. 

20 million seems pretty possible to me but it all depends on when the life cycle for the Xbox 360 ends. if it ends in 3-5 years then yeah i say that is pretty possible. But if a new Xbox comes out with in the next few years then no it won't. 

It WILL sell 20 Million units. Maybe even by this time next year.

It has the potential IMO to reach 50 Million. Especially if they use the technology on the next Xbox, and if they release it on the PC... There is a possibility of it happening.

Definitely a huge product!

Lol more like prime as hell.

Kinect sells more then Black ops for a few weeks, I can see it get 10 million by march 2011
