Nintendo’s recent unclear “clarification” of the Wii’s sensitivity to sunlight to 1up left something to be desired. Kikizo pressed a little harder, and got a company representative to admit that the Wii sensor bar can be affected by head-on exposure to sunlight, causing interference. Of course, if the sensor bar is directly facing sunlight then the television that the console is connected to would likely be affected in the same manner. So, it looks like the sun will kill the Wii sensor bar, but only in situations where the sun shines directly into the IR sensors.
