Microsoft global Kinect games marketing director Michael Johnson has confirmed global sales figures for the original Dance Central and Kinect Sports. Harmonix's dance game has moved 2.5 million copies worldwide, outdone by Kinect Sports and its 3 million global sales total. (In January, Microsoft's Aaron Greenberg confirmed that each had topped 1 million copies sold by the end of 2010.) Johnson also noted that Dance Central was the bigger hit in North America, while Kinect Sports fared better in Europe.

Kinectimals has final sold over a million as well so that's three kinect games that have sold over a million not including Kinect Adventures. Pretty good feat for MS.

I guess Kinect has to some extent been a success.....I just wish it had more quality games

It deserves it, especially Kinect Sports, that game is way better than Sports Champions or Wii Sports, but thats just me

This is very very old, they reported those figures months ago.
