Based upon sales of similar motion control titles on the Wii I feel like this is a very strong line up of titles for Kinect. Backed by a $500M marketing campaign I believe several of these games will gain traction and catch on with mainstream consumers.
4.14M (3rd party)
3.43M (3rd party)
2.29M (3rd party)
2.22M (3rd party)
2.11M (3rd party)
1.42M (3rd party)
1.41M (3rd party)
.89M (3rd party)
.85M (3rd party)
.79M (3rd party)
Most of these Kinect games won't do as well as their Wii counterparts have, but I think it shows that publishers are putting out games on Kinect that consumers want to play. At the very least you have to admit that Microsoft is making a very strong play to grab the Wii consumer.
