You're referring to Raytracing or other physical rendering approach.
This is still polygonal rendering but by real time they mean that it was rendered 1:1 live on a cpu.
Most games trailers actually render at some fraction of real time (12:1) (and often up-res everything) to a series of files which are turned into the actual trailer.
Also this is running on a pretty beastly machine. So realtime for them might be 12:1 time ratio on your machine at the same quality. Or much lower res and real time.
No. I meant high-fidelity rendering as was shown in the post. Of course Moore's Law will soon give us high-fidelity ray tracing in real time also. The new hardware implementations are a step in that direction.
As for "running on a pretty beastly machine", that's my point - Moore's Law says this will soon run on your phone.
