A camera on the wiimote? First of all, it would look ugly. Second, it would get in the way. Third, it would have to plug into the spot where the nunchuck plugs in, making it akward. Finally, everyone would hate it and nobody would buy it because of the terribleness of it, and it would be a failure. Now, a webcam might work, but that wouldn't happen for the same reason chatting or a headset won't happen online on the wii.
