I heard about this a while ago but until they can get it to work with only one console I don't think it would be used very much. It would be fun for those times when you want to play your 360 and someone else wants to play their Wii, but then the sounds get messed up, so maybe they should put little ear buds on the glasses too.
Yeah, I'm with Z. It's an awesome concept, but needs to work with just one console. And I love the idea of two systems at once.
