One of my biggest problems with the "Guitar Hero" games is that as close as it is to playing the real guitar, there's fundamental differences that totally blow the reality.
Looks like Rock Band has solved that problem. They've teamed with Fender to make a real guitar that works as the interface. While it's not as cool as say plugging my Les Paul into the game, I realize that's impossible as this Squier has sensors running up the neck itself. Still it should fundamentally change how musicians see the game.
But will it work for the Beatles version?
