There has been word that there may or may not be a sequel from information from many different sources. In an interview with IGN, co-founder John Carmack stated that he plans to do a sequel to RAGE after Doom 4 ships. "We're about to roll the whole core tech team over to Doom", Carmack said, when asked what lessons the studio learned from developing RAGE. "After Rage certifies, the heavily-lifting code team will be migrating over to do new systems [for the Doom team]."
