Harmonix going dancing with Natal?

I just can’t seem to wrap my mind around word that Harmonix is developing a dancing game for Project Natal. Yes, a dancing game for Natal. While the developer is still finishing up Rock Band 3 the fact that the keyboard — keytar? — might be coming to the plastic instrument ensemble cannot diminish the image of me gyrating uncontrollably in front of my television to the latest dance hits. *shudder*

Nothing has officially been announced, hence the question mark at the end of the post’s title, but it has been heard that the recent spat of dance song licensing has been for this new Natal-based game. No word on if the rumored project might be designed for the PlayStation Move.
