@noiob I mean, the "sensor bar" was just two IR lights, whose functions can be replicated with two candles spaces about a foot apart. It's badly named because there's no actual sensor in it... so it'd be pretty easy to build in to a TV. Wouldn't even have to plug into a console.
@hache I know how the sensor bar works I was asking whether the Wii was popular enough for someone to integrate it into a screen's bezel
