Like this is any surprise.
MCV talked to Alex Rigopulos, CEO of Harmonix, and Kasson Cooker, project director, and they've said that the sequel to the upcoming
Dance Central is already in pre-production. I'm sure they have a lot of ideas and they're putting them in future games so this doesn't come as a surprise.
Dance Central looks to be one of the more intriguing titles that's coming out for Kinect and whenever I walked by the E3 booth, there was always a crowd around the game. I'm guessing it's going to be a big hit and Harmonix has a long roadmap for a series of Dance Central games.
