Interesting article, but I don't think it speaks to the issue of Crysis2's average review score.
Crysis2 got high scores across the board because it's basically a pretty good console game. Reviewers aren't going to delve into the morass of the PC gaming world when they know they're going to come up with is a handful of dirty muck. The last time a Gamespot editor spoke his mind about a major release by a corporate monster like EA, he was "asked to resign." That's the real reason why you won't see Crysis2's many PC issues on a major gaming site. Nobody is willing to put his/her head on the chopping block when a titan of the industry like EA is swinging the ax.
