I think it is true but it is hype. Assuming it is based on voxels, then the earliest game engine to have used the technology (to my knowledge) is probably Blade Runner circa 1990s. The hardware at that time, ofcourse, dictated the quality of the tech at that time. By extrapolation I would say this is very much possible but may not be such a huge deal as it is made out to be. The results however could be amazing if widely adopted by the industry.
