This recent slew aren't technically voxel games. At least not in the sense of NovaLogic's tech - see: http://news.ycombinator.com/item?id=2447057.

(To add to the confusion, this particular game, Ace of Spades, actually is voxel-rendered.)

It is however thought that John Carmack's next engine after the Rage engine may include honest-to-goodness voxel rendering: http://en.wikipedia.org/wiki/Id_Tech_6

Historically, Carmack has had quite a lot of influence on both the hardware and API vendors, so it will be interesting to see if he can spearhead more mainstream movement towards sparse voxel octree rendering: http://youtu.be/THaam5mwIR8
