Harmonix has ideas for what the next entry in the Rock Band series could be, but the game is not in active development right now, the Cambridge, Mass. developer said today at PAX East.

"No, we are not making Rock Band 4; it is not in development; it is not actively being produced in the studio. We have thoughts about what it could be and would love to put it out," director of publishing and PR John T. Drake said today.

Yesterday during the keynote address at PAX East, Harmonix CEO Alex Rigopulos said Harmonix has "grand plans" to revive the Rock Band and Dance Central franchises for the "coming console cycle." This would presumably mean Xbox One, PlayStation 4, and Wii U.

Also during the Harmonix panel today, Drake talked about the company's new free-to-play rhythm-runner game Record Run, which is said to launch "soon." It will roll out first for iOS devices and later for Android. As for Windows Phone devices, Drake said, "We're ambitious; we're not crazy," going on to note that he is a fan of those devices.

Finally, Drake teased that Harmonix has a new game to reveal and its announcement could be imminent. "We'll have another game to talk about soon, which is pretty cool," Drake said. Unfortunately, no other details are available.
