If there should be anything 3D, it should be like this, not with glasses, glasses only are good to turn your eyes backwards.
But now, get your mind back to the old controller trailer, from TGS last September. There are two (at least) games there that can actually be suggesting some sort of 3D holographic output device.... Namely, the dentist one, and the one where the 3 girls are killing flies, or whatever. A game about killing flies, the way they move their eyes, etc, it suggests a 3D environment.
Now, of course it's just a trailer, a marketing move, but who knows?
I'm not putting any money on this, it's just something that hit me now as i rewatched the trailer, which I hadn't seen in a few months. The killing flies thing made me think about it...
Also, notice that no one in that trailer is wearing any type of goggles.
