On Wednesday morning (September 9), "The Beatles: Rock Band" hit stores, much to the slavering delight of fans around the world. But before there was a video game based on the Beatles, there was only "Rock Band." MTV News spoke to Josh Randall, creative director at Harmonix (the developers of the "Rock Band" games), to find out how to follow the biggest act in the world.

"Rock Band" has always been about highlighting multiple bands in their games, until "The Beatles: Rock Band" came along, that is. Is this going to become a trend with band-specific "Rock Band" titles? "Obviously, this was an amazing, special opportunity for us that came up," Randall said. "I think it's not our primary focus to do artist-specific games, but if certain artists came along and wanted to creatively engage with us and had good ideas for a game ... I think we'd be up for it."

So what artist would be huge enough to follow the Beatles? "There's a short list of some of the other biggies. I always say I'm a huge Devo fans, so, like, 'Devo: Rock Band,' " Randall laughed. "But we already have those guys as downloadable content in 'Rock Band,' so I can live out my own private Devo fantasy that way. But, yeah, we've got a short list. What I'm hoping is that 'The Beatles: Rock Band' will come out and, if people are impressed with that, that'll lead to future conversations. We'll see."

With no solid news to speak of, we asked Randall to comment on rumors that "Rock Band 3" has already begun development and will hit stores in late 2010. Randall was quick to respond with a sly giggle: "Never heard of it."
