We spotted this demo light gun on the floor of TGS2008. The cagey booth attendant wouldn't tell us if it will ever hit retail shelves, but the frankensteined (see the external batteries?) device was certainly working with a PS3 and projector here in Tokyo. We're all for some wireless light gun action, so bring it on, Light Gun Zero. That is, if you can. Oh, and if you can get rid of that unusual battery pack. Okay, thanks.
