Although Activision has denounced plastic guitars and miniature turntables,
Kotaku
is reporting that Dance Hero, originally trademarked in 2008, may be in development.
This is pure speculation at the time, although it seems to be a very probable scenario for Activision. Dance Central proved to be the selling point of Microsoft's Kinect in November, 2010. Meanwhile, Ubisoft is currently reporting that the Just Dance franchise has sold 10 million games worldwide.
