Mondays are for rocking

So one half of the team behind the brilliance of Guitar Hero II, Harmonix, is jumping ship (this is old news, not the focus of this post) to start a new venture with industry giants EA and MTV: Rock Band. It'll be a rhythm game, but with drums, singing, guitars... the works.
But how much will it cost? We already know they've signed up Fender as their digi-axe to power the game, which ain't cheap in real life. So, based on this price list, having a full band could be steeeeeeep. Then again, that's Gamestop - Harmonix is trying their best to do damage control, and I hope they're not just spinning. I'd love to get the band back together.
