What really blew me away was when he started carving caves into the rock.

There is still a big gap before using this kind of editor for a high resolution polished render.

Namely, what is missing among other things is :

• import and export to popular formats
• simplify seamless conversion of imported models into low poly (but high visual quality) versions to use in the editor
• conversion of the viewed scene into a high resolution model for full ray tracing (they could export scenes for popular renderers - VRay, Pov Ray, etc)
• director tools for animation (although they probably have something like that for cut-scenes)
• preset libraries of materials and atmospheres

The things is - they are certainly using a lot of tweaks and constraints to handle large scenes like this in a very fluid manner. But even knowing that, this kind of approach would make a fantastic scene composer / previewer where you could get 90% of the job done before taking a high def snapshot at the end.
