Exactly when he mentioned the pixels of a screen and only rendering for them, he made it sound new with his voice but it is just culling and z-buffering. Point clouds still have to do that. The reason why we use polys is for eliminating the math of all those points to make physics, shadows, texturing possible. I can see voxels/point clouds will be something in the future and voxels will probably be it, but this is silly to present static low quality work to show off a new technology for graphics. I wonder if it is not a joking jab at tessellation and voxel directions as DX11 and OpenGL 4 now have tessellation and voxel discussion by Carmack. It will happen but these things are slow moving.
