Rumours are buzzing around the interview that suggest Activision are working on a new franchise, which would effectively replace Guitar Hero and DJ Hero. It will be dubbed, Dance Hero.
Activision trademarked the name a few years ago, but Kotaku has learned that they plan to put it to good use. No platforms have been mentioned yet though, but it's safe to assume it will be on the big three.
The ironic thing, of course, is that Harmonix has already created a similar game, Dance Central. So it could spark up another rivalry between Activision and the Guitar Hero creators.
