Kinect Sports shifted 3 million while another Xbox Kinect game Dance Central sold 2.5 million copies since the Kinect titles first went on sale in November 2010.

In terms of regional popularity, Kinect Sports was a bigger hit in Europe, while Dance Central's best performance was in North America, according to Microsoft's Global Marketing director Michael Johnson in conversation with games website Joystiq.

Little wonder, then, that both will see sequels come late October. Kinect Sports: Season Two and Dance Central 2 launch October 21 in Europe and October 25 in North America.

For Dance Central 2, that's three weeks after Just Dance 3 takes to Wii, Xbox Kinect and PlayStation Move.
