Something really special: augmented reality displays.Unless this is a complete hoax: it is possibly the most compelling demo I've ever seen. This stuff makes me believe in magic.
I'm sure that this is just wishful thinking but we have a confluence of several video game rumors that suggest a not too taxing scenario. 1) Nintendo implys that their next generation game console won't hook up to the TV. 2) Microsoft names their second generation XBox: XBox 360. Will the next generation of consoles use a technology like this to bring gaming into real space through goggles or glasses?
One thing is for sure: screens on TVs and monitors will keep getting manufactured bigger and bigger until the broadcasted image fills our entire field of vision. Only then will the TV ever be concievably "big enough." The only sensible realization of that goal today is through a display that sits very close to the eye.
