Rock Band 3 senior designer Brian Chan is working on a new project for Harmonix, intended for three platforms that rarely receive the same games: XBLA, PSN, and Facebook.That's about all the detail we have on that project, other than that Chan is working as lead designer -- as this information is straight from Chan's resume. Of course, judging by Harmonix's history, it'll either be a music game or motion-controlled hoverboarding.
Harmonix was reticent about the project when we asked, unable to give us a clear answer due to the positioning of tongue in cheek. "As we've stated before," a representative told Joystiq, "our studio is growing and hard at work on a variety of titles. In a storied Harmonix tradition, our designers start working on those games before they're publicly announced." Harmonix will have more information "in the coming months, probably via a LinkedIn update or something - we haven't decided."
