Rock Band Chosen

I have made my decision. I can cross Guitar Hero III off of my list of games I'm getting this holiday and add Rock Band onto it. After watching them play it on The 1up Show and listening to remarks about the game on various podcasts it looks like Rock Band will be getting my money rather than Guitar Hero.
One huge reason it will be is that I have two other gamers in the house. I don't want to have to fight with them over who gets to play now. It will be better pool our money to get Rock Band and we can play at the same time.
Another reason is I want to play other instruments. Don't get me wrong I will probably spend much of my time with the game with the guitar, but I would love to try the drums and singing. The drums look hard but could be very fun if you learn how to play them.
Well as soon as I get the game (see post below) I will post my personal review.
