does each screen show 1080?
but yea i was wondering this too.
Recall the sony conference and thier 3d tv and how they boasted about with these glasses you can have your own screen with splitscreen for 2 player
If this could support 4, or hell you said 8. you could have 4-8 player FPS games with each person having own screen, and then have the main tv be like a cinematic movie type of camera following and looking randomly in on stuff going on in game. like it zooms in an shows fire fights going on and so on
