I thought the video still looked pretty bad (maybe because it was actually the PS4 version? /cheekiness).
So they actually managed to get tessellation into this game, but not other console games?
A lot of console only devs are just getting to grips with the newer techniques afforded by modern GPUs and are focusing on getting physically based lighting engines up and running first because that can have such a dramatic effect on materials rendering. Tessellation will probably be in the second and third year titles since it's more focused on minute details.
