It looks mind bogglingly good.
They had better fix the embarrasing input lag this time though... 150 ms in killzone 2 was a new low in gaming, in a league of it's own of badness.
30 fps for the next game means input lag 'll be shitty to begin with so they'd better work on their engine.
Maybe they should ask carmack for some help ... that man is a god at this kind of optimisation, guerilla have good artists but on the technical side the input lag suggests they have no frigging clue about how to design an engine fit for actual interactive gaming and not just cutscenes.
KZ3 had very low input lag. Not worried about that for SF. They just need to bring KZ2's recoil and momentum back.
