There are wireless sensor bars? Strange... seems kind of pointless because of the battery issue.

The idea is if you have a big enough tv that the wire is defeated, or some other such thing. Or if you want to be totally wireless besides the a/v and power cables...

I got my wireless sensor bar, wii remote, and nunchuck long before i got my wii (with compatable bluetooth to usb adapter you can use the wii remote and such on your computer) And when i got my wii, i got it used for $50, it came with nothing.

I'm seriously wishing i had a wired sensor bar now though...
