Remote would control the lightsabre, obviously. It should be free-form, in that as you move the remote, the onscreen sabre moves, too. Also, since the analong "nunchuck" has motion-sensing capabilities, too, it could be used for force powers! Push forward to do a force push in the direction you push. Pull back for a force grab. Pull back and quickly pull up to do a choke and mid-air suspension... all while fighting a second guy with the sabre! The analog stick moves and it could use Metroid-style controls to lock on to a guy during sword combat so that you won't have to worry about strafing.
