I går aftes leverede Harmonix beskeden om at Rock Band 3 som forventet er under udvikling. Vi kan forvente at se næste udgave omkring juletid. På Rock Band Facebook-siden skriver de følgende:
"Harmonix is developing Rock Band 3 for worldwide release this holiday season! The game, which will be published by MTV Games and distributed by Electronic Arts, will innovate and revolutionize the music genre once again, just as Harmonix did with the original Rock Band, Rock Band 2 and The Beatles: Rock Band. Stay tuned for more details!"
