Harmonix has said they're planning to bring back
Rock Band for the PS4 and Xbox One sometime in the future.
He prefaced his talk this morning by saying he would not announce a Rock Band 4 or Dance Central 4 and he did not say if these games were in fact in development in any way. However, he stressed that both franchises are "near and dear" to Harmonix. He went on to say that the studio plans to bring these franchises to the "coming console cycle" "at some point" and with "guns blazing."
