So, is the writer of this article partially sighted or something? Because what he says makes no sense unless he was playing Crysis on a PC with the bare minimum spec. Not only has nothing come close to what Crysis acheived on high to max settings, but it also had a lot more to render than the urban environment of Crysis 2. I wouldn't be suprised if part of the reason Crytek chose New York is actually because it's easier on the hardware.
Off topic: If Crysis 2 is set 3 yrs after Crysis 1, what happened to Nomad and Psycho?
