"We've actually made a choice to break out of the annual release cycle for Rock Band this year," Rigopolous announced at the conference. The Harmonix CEO cited a partial reason for decision was because, "annual cycles place limits on the choices [a developer] can make" and Harmonix would like to think long-term with its music platform.
According to Crispy Gamer, when asked about EA's reaction to the promise of not releasing Rock Band 3 this year, Rigopolous confirmed they were understanding of the decision. "They know how important this series is and they're willing to give it the time it needs," he said.
Currently, Harmonix is hard at work developing a new title based on The Beatles catalog of music and indicated with that license sewn-up, the developer would like to work on bringing Led Zeppelin into the genre, in the future.
