Guys, I think he clearly said that it was just a real-time Google sreet view.
Also what graphic engine could be capable of such visuals including all the little details we've seen there ? Tell me.
If you have a little knowledge about computers you would probably agree that no computers (even top ones) can handle something like that. It's too early for photorealistic graphics.
He did not say it was a real-time Google street view. He said, "think of this as a real-time Google street view."
