May 10^th, 2006 (3:38pm) - Some new images have surfaced of the sensor bar that comes with the Wii game console and the light-shotgun add-on. The sensor bar is necessary to measure the distance of the Wii controller and player from the screen, creating a center point for accuracy and calibration, and the shotgun add-on will help immerse players into action games and light-gun shooters, such as the Wii’s sequel to Duck Hunt.
