I'm sceptical. If you consider how much memory will be needed to store all those points, let's say they were just true colour pixels - and your PC has 32gb of memory... you have the memory to display a block of 2000x2000x2000 - that is hardly infinite, in fact that's fairly finite IMO - and that's just colour information.
Then what about animation? - each of those points would need to be calculated and adjusted according to a moving skeleton. That's fine when your talking about a couple of hundred vertexes per bone - but when your adjusting millions of points, that's not viable. I haven't seen any videos with animation in them.
Also, what has progressed in the last year? - no new images, no new videos, no news...
I think it has it's applications, but videogames are not one of them, and never will be (at least not in my lifetime).
