because every human and animal has the right to privacy and it's people like you who ignore the little things let our rights disappear. Besides the Wii needs the sensor bar to receive the signals transmitted from the remove. Kind of like how a wireless mouse. That is all it does. There is no reason to have a camera on a console if you are going to use a controller. Camera's only capture light and create images, they do not transmit and receive controller signals.
It's not the government forcing you to have a webcam in your house. If you buy it it's not abridging your "rights".
And if you want to learn more about your precious rights, look up "Japanese Internment 1942", "Guantanamo Bay", and "Arron Swartz"
Anyways on topic.
The new xbox is pretty damn ugly looking anyways. It's probably going to flop.
