It's pretty much a given that you'll need a good CPU and 580 level card to make it look like that though.
Thank god, the more "crysis/farcry" type games out that push hardware forwards and the other games companies to match the quality of the best stuff out the better, thats the best possible thing for PC gaming, games that push the need for more hardware and games that set a benchmark other companies have to match.
You bring out a game that looks like that and the COD guys will have a game that looks so old in comparison they'll finally make a new engine and push forwards, and then so will someone else, then so will a dozen other companies, and then the need for the next gen of consoles comes out to keep console gaming even slightly up to date, and the whole industry moves forwards, fantastic.
As for saying this is a marginal step forwards, not even slightly.
This is what people seem to not be understanding, and Pottsey if you read the gpu forum simply doesn't understand in terms of gaming complexity.
Diminishing returns, the harder the newer effects get the more power they take to use. Pottsey thinks mobile gaming is catching up because you have a few games on there, but prebaking textures and very basic lighting take next to no power, half decent lighting takes a HUGE amount of extra power and insanely high quality lighting will take massive amounts of power extra again.
But realistically, if that is in game footage it could easily be the best looking game to date, animation, I said it was small changes and it was, but its actually going from a model with only a few pivot points to something with far more complex motion, but that brings a heck of a lot of other downsides, AND bonuses to it.
The downside is buggyness, instead of making sure clothing doesn't clip and looks realistic with just the arms moving back and forth, now you've got to check everything looks right when the arms move left and right, when the shoulders move, when the shoulders move relative to the hips, etc, etc, etc. Its exponentially more complex even if the actual movement itself is only a minor adjustment. However the realism of their movement is something I've not seen before(in a real game, or a real time tech demo).
An advantage off the top of my head, is potentially better hit detection as each part of the body gets more complex and more complete, and in terms of seeing a guy get shot, rather than just a chest hit and ragdoll effects where 4 points swing about rather daftly, the guy can now be shot in the left shoulder, and he can spin and move as if hit in that left shoulder specifically, again adding to the realism.
The closer you get to "realistic" looking effects, you'll be looking for exponentially more power and complexity to achieve it.
ANyway as said, the more one game pushes the more other games have to push to follow.
I mean this comes out and looks like amassive leap forward, and Dragon Age 2 comes out and looks like a massive leap backwards..... Bioware/EA will look like idiots and their next game will most likely be a massive leap forwards.
