a sequel would be cheap and would probably sell ok. It's up to ubisoft if they want to ruin just dance by releasing the sequel right away. If they release a sequel it will sell far less than the first one and the if they really want to make it a franchise they wouldn't release it because it would destroy the franchise not build it up. They could probably make a pretty good profit even if the sales went way down but they better not complain when it sells like crap and the franchise is ruined.
