Oh yeah! I am stoked for World Tour, despite the fact that I'm something of a Rock Band Loyalist. I feel like Activision just assimilated Harmonix's franchise and has been borrowing concepts from them ever since.
I really love the band camaraderie that comes from Rock Band, so I'm eager to see how well World Tour compares. Sure, just playing the music together is part of the experience, but so is the customized band name, logo, motto, and post cards that Rock Band gives you throughout the game. I know world Tour finally allows for fully customized characters, but I haven't heard much on how customizable the band concept is.
While I like the six input drum scoring World Tour has to offer, I really don't care for the Drum Set. I think it's aesthetically awkward and the cymbals feel cheap. I prefer the design of Rock Band's drum set, but I like world Tour's scoring. I have the Ion Drum Rocker premium drum set, However, so there is no chance I'm buying World Tour's set.
On a final note (pun intended), I just have to ask why a game about band music is entitled "Guitar Hero"? I know it's the so-called continuation of the franchise, but it sounds to me like guitars are still the emphasis there. If Activision has indeed been copyrighting a number of music related game titles, would it have hurt them to call it "Band Hero" or "Music Hero"? The benefit of such a franchise title would be the opportunity to expand into a much wider variety of music other than rock.
