He wasn't claiming
Can you honestly not imagine, oh, I don't know, some crazy and ludicrous hypothetical situation where two people own one console (a young engaged/married couple living together, siblings, you get the idea) and would want to play multiplayer together on it with each other but don't want to deal with the split screen? How about having friends over! That's a case where one person owns one console but would appreciate this technology. Since this requires a 3DTV, it's not going to be tiny either, which means no cramming together and smelling each other's asses is even necessary!
Do you have that much trouble thinking outside of your own little world, or did you just want to come in here flexing your "back in my day" memories? Or do you just believe that everyone should be like you, that is to believe that networked multiplayer gaming is the only kind of gaming?
This doesn't happen on my home machine, so I can only speculate it has something to do with the video card/driver implementation/whatever of directx.
