It's not shocking to learn that Ubisoft is probably working on another entry in its Just Dance franchise. The groove-thang shaking simulators have been massively successful for the company, and tend to sell well after release, so frankly we'd be more surprised if Ubisoft wasn't cranking out another one. But thanks to a domain registration, we might have a name: Just Dance Propel.
Joystiq reports that the domain was registered on March 2. The URL isn't live yet, but a check of the domain shows it owned by Ubisoft Entertainment. We wouldn't be surprised to see another Just Dance game, this time with a subtitle instead of the telltale numbered naming scheme.
Just to give you an idea of the staying power of Just Dance titles, Just Dance 3 was released in October near the big-budget fall titles. Four months later, it still claimed the #5 spot in the February NPDs released last night, ahead of Battlefield 3 and Skyrim, and the more recently released Soul Calibur V.
