Just Dance 4 announced, coming in October

Ubisoft's E3 press conference kicked things off with a little dance number, and an appearance by rapper Flo Rida to announce Just Dance 4. The successful franchise is known to keep you dancing in your living room solo, or with a group of friends, but any changes or new features were not shown. We do know that it is coming to the Wii U this time around, and will be out later this year in October. Update
