Kinect's two major sellers, Dance Central and Kinect Sports, have topped major milestones.
Kinect Sports has drawn 3 million sales, while Harmonix's Dance Central has passed 2.5 million.
Kinect's global marketing director Michael Johnson told Joystiq that Dance Central is more popular in the US than Europe, while Kinect Sports enjoys the opposite configuration.
Kinect had sold over 10 million units worldwide in March, and has performed strongly in the intervening months. Dance Central and Kinect Sports are the motion control system's greatest sellers.
Both games will see sequels this October.
