First, the new guitars not only look better, but they will include some welcome hardware tweaks. The new axe includes an optical sensor that will make syncing the game to your display a breeze. Rather than go through that annoying tap..tap...tap synchronization scheme, all you'll need to do is hold up your controller to your display and it will figure things out with you based on your screen's refresh rate. In addition, the new guitars have been updated with slicker fret controls that make it easier to slide from one to the other. Meanwhile, the strum bar has been tightened up a bit. No clicking, though -- the guys at Harmonix say no one "dreams of playing a metronome" anyway. A dig at Guitar Hero? Perhaps, but if you're looking for some click feedback from your controller, look elsewhere.
