Its the new 3D modelling technology.
Actually it's not new, this tech has been around for quite some time. This particular company have been trying to get funding for this project for at least 8 years.
The pics you are showing to us are taken from a ''modified'' game.
What is your point? It's polygon models with higher res textures than the standard game had.
And its not imposibble to animate models made of dots. You just group the dots and move them.
Did you notice that everything in that video is perfectly still, and that they only achieved 20 FPS with absolutely no animation?
Theoretically it is possible to animate, but current hardware is simply not capable of it (and probably not for quite some time).
