Rock Band preparing a new, next-gen IP?

Next to prepping Rock Band Blitz, developer Harmonix is keeping busy with something on the side as well.

A new intellectual property for the next wave of consoles appears to be in the works, and it sounds like something the studio hasn’t fiddled with before, with job listings looking for narrative, content and level designers, plus a software engineer to assist with “a unique motion-gaming IP.”

“Harmonix seeks an accomplished Narrative Designer to incorporate creative story lines into gameplay on a unique motion-gaming IP,” reads a listing.

The phrase “music-based motion-gaming IP” is also thrown around.

Rock Band Blitz remains the studio’s only currently announced project. It’s expected in this summer on XBLA and PSN.
