It is coming out. But not for a while. And I don't think that they should add singing and drums, even if they already are, it won't be that good. It's like Indiana Jones 4 and the aliens. It just doesn't fit.
sorry forgot to put link in http://www.guitarhero.com/ it needs to be updated though so they don't have a lot of vids about it i think its coming out sometime in autumn (fall)
aerosmith edition looks good though i think i'd prob get bored of playin the same bands songs over again i prefer a little diversity thats why im just gonna wait till GH4 and i may need to save up as since its got the drums its prob gonna cost more
DUDE listen to me... aerosmith is another totally diffren game..not supposed to be guitar hero 4... guitar hero 4 is coming out bye the way and its gonna be like rock band.. but just WAYYYY better cuz you could customize your guitar AND your own SONGZZ!!!!!!!!
Yes. I have found out much info about it. Apparently, it will have much more than any other Guitar Hero game to date.
In this game, apparently, there will be not a set path of Campaign, but a duel path, or more paths. Also, there will be the ability to create your own character.
