Heh, Crysis is still almost the benchmark 4 years after release! The Witcher 2 is the best thing I've played in the last 2 years in terms of all out splendour.
For art direction, design and ideas Skyrim fares better, Dark Souls/Witcher 2 pips it for me though.
edit: BF3 is pushing the limits a bit too and deserves a mention.
Lol wut? comparing a console game to Witcher 2!? Blasphemy!
But yes, Witcher 2 has some amazing visuals and particularly character models. The animations are occasionally off, but it's a relatively low budget game IIRC and still gives out free content so it's all good.
Here's a couple of screenies for people who haven't seen it:

Battlefield 3 isn't even nearly as pretty for the most part, although some of their facial modelling is nice:
