I can't wait for it either - never taken a look at S.T.A.L.K.E.R. before though as I heard the last 2 games suffered a lot of bugs, although I hear the third doesn't have a lot of that.
Skip Clear sky, it's based much more on gunfights then anything else, Shadow of Chenobyl and Call of Pripyat on the other hand are amazing. Two of the most atmospheric FPS's you'll ever play.
On the subject of Metro2033 though, just found the 'optimum requirements' on steam:
Processor: Core i7 CPU
Memory: 8GB RAM or higher
Graphics: NVIDIA DirectX 11 compliant graphics card (GeForce GTX 480 and 470)
DirectX®: DirectX 11
What the holy crap is it going to do with 8gb ram?! Let alone an unreleased 400 series...
