Having launched last week, MTV Games' Rock Band no doubt benefited from the Black Friday shopping madness following Thanksgiving.

Said Banc of America Securities analyst Jonathan Jacoby, "From the comments of GameStop management, it seemed they expected to sell out of their initial batch of Rock Band over the Thanksgiving (Black Friday) weekend." Jacoby expects more than 800,000 units of the game to be sold by the end of this year.

And while the hype around Rock Band continues to generate sales this holiday, it seems MTV is already conjuring up its next big idea. Speaking to Reuters/Hollywood Reporter, Jeff Yapp, executive vice president of program enterprises at MTV Networks Music Group commented, "We're pretty optimistic about what this game is going to do. But our next big announcement, which is coming up fairly quickly, is a move to a whole other realm."

What MTV has planned for a "whole other realm" is anybody's guess, but one thing's for sure: they won't be lacking funds. Parent company Viacom pledged earlier this year to invest over $500 million in the video game sector.

Interestingly, Harmonix CEO Alex Rigopulos also justified Rock Band's high price ($169 for the game bundled with a guitar, drum kit and microphone) by noting that it's more than a video game. "We don't see this as just a game title -- it's a platform in the same (way) that you spend money to buy a stereo system or a game console," he said. "With downloads and new content that we'll be making available on a weekly basis, you can continue to expand and tailor your play experience."
