Exactly. Guitar Hero needs to go back to only guitar. Even though Activision changed a lot when they took over with GH3 I still loved it because it was a great game for mindless shredding. I even liked GH:A, but these GH Band games need to go.
As far as The Beatles we'll have to wait and see...It's common for a song to come out as DLC that turns out to be a lot harder than it sounded like it would be (Snow) so maybe The Beatles have songs like that. If not, I guess guitar just won't be the focus of the game lol
