Using a 3D tv with two pairs of glasses, you can feed two separate 2D video signals to the viewers wearing them. They actually demoed this at the IFA show, with two movies playing on the same screen. This could be effectively used to allow multiplayer modes where both players get a full screen, on the same tv, without being able to see the opponent's screen. Pretty awesome, methinks! Only issue would be the sound, both players would need to wear headphones so they only hear "their" sound. This can be done though, on the tv demo mentioned above, the 3D glasses had integrated earbuds. My question is: Why isn't anyone jumping on this??? Of course it's a matter of processing power and memory resources, but really, NOBODY has given this a shot yet? Not even as a gimmick, "look what we can do"? It was the first thing that came to my mind when I first played a 3D PS3 demo at the IFA 2010. I couldn't wait for developers to start experimenting with that....and two years later, nothing??
