The sales of Guitar Hero have nothing to do with it. Guitar hero is a game like rockband, it's on its own. 80-90% of people who play rockband are non gamers. A large percentage of that bought the 360 arcade JUST to play rockband. Thats why it sells more on the 360.

Can you send me a link which can proves your claim or you just find that by yourself?

I guess it would be hard to statistically prove that those who play rockband, don't play games.
