The original message, posted on a Nintendo.com message board mentions the Nintendo sensor bar (to communicate with the WiiMote) can have a breakdown in communications when hit by direct streaming sunlight.
The original quote talked about the Nintendo World Event in New York City, and the writer said:
"We know that the sensor bar goes all wonky when halogen lights are in the room. But did you know that natural sunlight messes it up too? That's right, if you have the sun beaming right onto the sensor bar, it doesn't work. For about an hour or so, the sun shone right into the store, the two MP3:C kiosks had to have curtains above them, and the Wii Sports Tennis and Shooting Game kiosks were unplayable since they were "shrouded" in sunlight. Later the sun went behind a building, and everything was in working order again. So when you get your Wii, don't play it in the sunlight. Or keep the sensor bar and TV away from the windows."
Today, 1up.com called up Nintendo to ask them to comment on this situation. They stated "Our testing thus far shows no great risk of light interference when playing a game that relies on the pointer and sensor bar." That doesn't speak volumes of confidence. Something like "no, this is an unsubstantiated rumor that is completely false" would have given warm fuzzies.
Nobody has a Wii to test the theory so this comment is all we have to counter the original posters comment. This leaves us with more questions than answers. Although, many people probably won't be playing the Wii in direct sunlight - and how many people use Halogen lighting in their game rooms?
It does seem to be some type of flaw in the design, perhaps minor. If the system has difficulty playing in the light could we find ourselves dying more often than not when playing in the afternoon or near a bright sunny window?
Nintendo should have answered the question like this: "If it is sunny and you are playing video games, perhaps you should go outside and enjoy the day." Now, that, would have been funny.
