I think it will stay that way for the simple fact that Rock Band DLC is supposed to carry on to the sequels! I don't think Activision would do that since they want us to spend as much money as possible.

While Rock Band will probably be superior, EA and Harmonix blew it by not releasing it sooner for Wii, or in Europe. They'll only have a few months before zillions of GHIII owners will be able to upgrade for cheaper and with fewer accessories all over the place.

But I bet Harmonix is already working on the next big thing. Hip-Hop Hero this Cmas?

Sooner or later rock band will have to come out with another one
To be honest once you get past the whole band aspect rock band sucks. It isn't a challenge after awhile. Also the online mode is horrible and the equipment breaks on a daily basis. GH3 will destroy rock band for the wii and ps2 and maybe 3. I was going to get rock band wii but now im not. There is so much too do it seems fake, custom songs online head to head rock band battles, the biggest settlist ever and DLC for the wii

Is it just me, or did everyone miss the fact that this is a totally separate game from Guitar Hero 4? Perhaps that was implied in some of the comments, didn't sound like it.

Also on topic, Activision milking of Guitar Hero has officially begun. They will kill off its popularity within a couple of years, sadly. This franchise is guaranteed to be the next Tony Hawk by 2012.

for some reason i feel that this will cut its sales,as it will be to expensive for many people

 That would be Guitar Hero. They have some how found a way to do the impossible and add dlc to the Wii version. When Harmonix gets around to making anything other than a half-assed port they put no effort into we might get a real version of Rock Band on the Wii, but it will be a while I think.

Aerosmith, DS version, and GH 4. The Aerosmith one is the only part that makes me fear for how milked the franchise will become. Seeing the list of mprovements in GH 4 (and not all of them are from Rock Band) I have a lot of faith in the series. It will eventually collapse on itself, but it will still take a while thanks to competition.

I just love how it's called GUITAR Hero and has all the the new peripheral. (No matter how many words you put after the title to make it sound more universal, sticking "GUITAR" in there makes it look... simply retardedly contridicting.) Originality = Gone?
*Sigh*
