According "jeux-france.com" (and "nintendo-vision.net" who talks about matt Cassamassina of Red Octane (?)), Red Octane, has just announced that GH III will be released on all supports, including Wii

just a question : what about GH 2 ?

another question : Matt (of IGN) works for Red Octane ? 

GH 2 is supposed to come out on the Wii as well.

Personally, I've never really seen the appeal in Guitar Hero.  It's nice if you're into that kind of thing, but I wouldn't shell money out for it.

Then again, I've also never enjoyed DDR. 

I'm not a big guitar hero fan, personally. Its dance dance revolution for your fingers, IMO.

But it is insanely popular. I think Guitar Hero has done more to expand the casual gamer market than anything else so far 

 They have that, actually.  Step Mania:   http://www.stepmania.com/

Cool, I just hope they all have equal online support (except maybe PS2 version).

what would be cool is if they actually made guitar hero so that you actually had to learn the fingering and the chords for the songs. I'd totally be into that. None of this 5 button hoopla
