Keyboard trailer for Rock Band 3 looks challenging

Harmonix has put out a new trailer for Rock Band 3 featuring the new and long-awaited keyboard.

The gameplay footage plays out like one would expect a keyboard interface to: a vertical piano roll with colored shapes meant to match with corresponding notes. The game also seems to offer players a nice option to change the on-screen interface from a realistic keyboard layout, to the familiar Guitar Hero-esque layout.

And like every music game, the trailer puts out a healthy list of songs and artists featured, so do take a look and see if you favorite bands have made the cut.

Rock Band 3 is set for October 2010.
