Ubisoft gets this party started with the announce of Just Dance 4

Ubisoft has started their show off with the announcement of Just Dance 4. With Flow Ryder singing, and pretty girls leaping across stage, Ubisoft has revealed just a few of the new songs that will be featured in this title.

Unfortanetly the stream I was watching cut off the release date, though I believe I saw October 2012.
