Is Guitar Hero starting to fade off?

[P3MA]

I'm not sure how you guys feel about this, but I feel that the hype guitar hero is now starting to fade away a little bit and in a matter of 3 years will become what DDR has become to freestyle players. I think that red octane is overdoing themselves by releasing so many different titles at one time. Also, with the arcade launch (which I did get to play at 2 different machines, wasn't a big fan) they shouldn't also release 2 extensions of guitar hero (DJ and Band Hero). I feel that there is less quality put into these games. What's your opinion?
