The PS4 would be capable off running a game with those kind of graphics as for current gen console tech, I'm not sure.
The PS4 is a pussy, unless I read the wrong specs somewhere. Claiming it's as high level as today's best gaming computers when it's really go the specs of a medium leveled gaming computer from 5 years ago made me lose some respect for them.
As for the animation, I did notice some fallacies in it but obviously they aren't going to achieve absolute perfection for quite some time. I do have to say though that this takes the cake as far as realistic animations go. I've never seen better, and probably won't for a long time to come. I hope when we make the shift from console gaming to virtual reality, the graphics look this realistic, or at least close to it.
As for those paintings, the first 2 are pretty good, but I have paintings in my house that look more real than the rest of those.
