According to the survey, Dance Central 2 would possibly include online store, more customization options for characters, and extra practice options – a lot like Rock Band.
There’s even a possible karaoke mode listed, which would allow folks to sing and dance at the same time, as well as online play over Xbox Live.
Here’s the list of items asked about in the survey, courtesy of Kotaku.
