Basically, I think it would be a ton of fun with a group of people, or if you were just doing the drums or vocals on your own. But Guitar/Bass... meh. I guess if they release stand-alone peripherals and the game, it would be easier just to use the old guitar to save having to get a new one for something you might not use a lot.. and then get the drums and mic seperate.
Edit: The most promising song -so far- looks to be Boston - Foreplay/Long Time
It's the only one I've seen so far with some good solos.
Edit 2: This is being reported as the hardest guitar chart in the game. Which, other than the freebird-like up/down parts, it doesn't look that challenging. Not saying it doesn't look fun to play, because it does... but - that's the hardest?
