I think it's a shame that it's taken this long for companies to expand more towards simulating the actual controller, and have elected to retain the same incredibly simplified mockery of the instrument, like with the guitar. It's great that people can feel like an awesome musician playing to a packed auditorium with just pressing coloured buttons and flicking a bar like they're actually strings, but each iteration should have been more and more demanding, in that the player should be learning key instrumental techniques, to the point where the difference between game controller and instrument, game-playing and music-making, is virtually non-existant. That's when you can say "this is both an excellent game and instrument-teaching tool".
Obviously a lot of people just wouldn't see the point, but as we can see, this evolution of the music games is required in order to keep the genre not only alive, but flourishing.
Anyway, sorry for the wall of text. TL;DR --> Games with real guitars would be awesome, make more of those.
I think Harmonix has done a commendable job of doing just that. The first
Rock Band introduced the drums which are quite close to their real world counterpart. And of course vocals can't exactly be faked... But as a fellow fan of the genre, I'm sure you know all that and would agree.
Now that we have authentic instruments, I think the next step will be some sort of system where players can use the software (it will cease to be a mere game at this point) to compose original songs and possibly sell them via the Rock Band Network. I'd be surprised if Harmonix is not already exploring this idea.
I really hope that RB3 proves to be something of a sleeper hit; it would be a tragedy to see them fall when things are just starting to get interesting...
