Ubisoft announced this morning that Just Dance 3 has surpassed seven million sales, with the Just Dance franchise cha-cha-chinging at cash registers over 25 million times worldwide. Just Dance 3, which launched in October, has been working it on the US and UK sales charts -- even offering private dance lessons at The White House.

US retail tracking group NPD previously stated dance game sales were up 326 percent in 2011 over the prior year. During Black Friday week, the Just Dance franchise sold over a million units, with Ubisoft stating it held 76 percent market share on dance games.

Just as a reminder, the Just Dance franchise includes: Just Dance 3, Just Dance 2, Just Dance, Just Dance Summer Party, Just Dance Kids 2, Just Dance Kids, Michael Jackson: The Experience, The Black Eyed Peas Experience and ABBA You Can Dance.

Don't be surprised if Just Dance 4 hits the scene in 2012, along with (at least) two other spin-offs.
