The game is coming out this fall.
At the Xbox E3 2014 event, Harmonix announced their next generation Dance Central title, called Dance Central Spotlight. It will be a low barrier to entry Dance Central game that will ship with 10 free songs, and then players haveto buy the rest a la carte. Songs will get produced for the game much quicker, as Harmonix has streamlined its production capacity to be able to create routines faster than ever. There will be more fitness options like profile tracking for weight loss and the ability to automatically create an exercise routine based on difficulty and rigorousness.
Dance Central Spotlight will be a download-only title and will release in fall of 2014.
