I have just recently completed construction of a home theater where I currently enjoy playing my 360. I plan(ned) on getting a Wii to add to the setup. The way I have it configured is that I have a 720p projector which is in the back of the room w/ all my stereo equipment, etc. It projects to a 96" screen at the front of the room.
My issue is this...consider this quote from Anandtech:
"The way the remote-like controller works is via an infrared sensor bar which is wired directly to the Wii and can be placed either on top of or below the television. The bar can be placed anywhere as long as the controller is pointing towards it. Some adhesive backing is used to apply the sensor bar."
This means that this "Wii sensor" will need to be at the front of the room, while all my A/V equipment for this projector setup is in the rear of the room. So for my setup this just simply will not work.
