So tell me this...
Aside from "production problems", just how much storage would you need to hold the maps from a typical modern game at a resolution of "64 'atoms' per cubic millimetre"??? Assuming each and every point needs, at bare minimum an RGB colour value and a light level, methinks (without so much as a beermat calculation) that the maps for an average game would probably need more storage than most sizeable research establishments have on hand, as evidenced by their small 'island' demo having 21 TRILLION polygons/data points/whatever.
It's a lovely idea in terms of prettiness but it's totally, totally unrealistic until we have storage devices with many, many thousands of times today's capacities... You don't have to look particularly closely at the example screens/vid to see that, while impressive looking, there's a hell of a lot of object repetition, which is presumably a careful way of skirting around the storage requirements problem. Everything is just a few stock objects rotated which obviously just wouldn't fly in a AAA title.
