In my opinion this isn't real 3D. But then again "Avatar 3D" isn't real 3D either. Well, I will admit to real 3D if there will be a holodeck.

Sure, we can do something on the PC for sure. Just track the face (or the eyes like Nintendo 3DS does) and adjust the objects on the screen accordingly.

I'm a bit sceptical how to make interesting gameplay with this new "feature" because in games 3D (with or without glasses) has always been more of a gimmick than a real feature.
