Even if it's absolutely impossible to animate this technology I don't think it would be "useless". I don't see why it wouldn't be possible to have the static elements (buildings, tree trunks, ground, debris, etc etc) of a level rendered using this tech, and polygons used for everything else. It used to be this way in the bad old days (Doom etc) - Polygons for level structure and sprites for animation. This would at least free up the "polygon budget" to improve the features which couldn't be voxel-based.
If anything you could create a pretty interesting art style with hyper-realistic backgrounds and cel-shaded characters, or similar. Even as a replacement for pre-rendered background scenery or out-of-level elements it would be useful.
And (thinking of the Game of Thrones titles story) whatever mojo they've got must surely be able to be applied to other industries, eg. CGI - if Weta or Pixar could improve the poly count of their static backdrops without just buying more rendering farms, that's gotta count for something.
"polygons for everything else" would mean you integrate two completely different rendering methods in one pipeline. I won't say that's impossible, but it sure sounds non-trivial.
