Wondered where these guys had gone.
Not to be too pessimistic, but there are a few points:
* The storage requirements of so much detail is large, very large. Even given a very efficient sorting and filtering algorithm, you can't get over the fact that such detail requires a lot of storage.
* Animation... never seen any with this system. Without animation it's all dull and lifeless. This isn't just animation of things sliding in various planes, it's about twists and bends as well.
* Reflections - still none. The "water" effect in the video is an inverted set of different coloured objects to give the appearance of a reflection. It's an acceptable trick, but now try combining this with trick with animation of the water surface... it's meant to be water, not a mirror.
* Still no sign of transparency, another important visual effect in graphics
* The scenes are extremely repetitive, probably due to having to keep the storage requirements even partly sane. Not even the angle of placement of the repetitive objects is varied, which does seem to indicate possible restrictions of the algorithms in use.
* Still no lighting and shadows, although the end of the video did promise that there are some. In which case, why not properly demonstrate this in the video, even if only a short clip at the end?
Not to say that the tech is without promise, but it's not far from ready for replacement of current tech.
