Longtime Gamespot.com Editorial Director Jeff Gerstmann was reportedly fired recently and the scuttlebutt on the internets is that he was canned over a less-than-glowing review of Eidos' Kane and Lynch.
Gerstmann gave the high-profile game a 6 out of 10--above average, but just barely--while, at the same time, Eidos advertising skinned the entire Gamespot site. Then, Gerstmann's employment ended, supposedly due to Eidos's unhappiness over the review.
While Gamespot's message boards are blowing up with flames and comments over the imbroglio (and Eidos apparently having shut theirs down), as of yet there hasn't been any official statement from the people involved about the incident(Gamespot, Eidos or Gerstmann), other than a confirmation that Gerstmann no longer works at Gamespot.
Since the sources of the rumor are not too reliable (unnamed employees, game blogs), this is all rumor and speculation right now. Maybe I'm naive, but while it's possible that gamespot dissolved the wall between marketing and editorial over one semi-negative review, I can't believe they wouldn't see the harm in permanently damaging their credibility with the gaming community over one opinion.
On the other hand, it's business, and perhaps CNet, the owners of Gamespot, really are that short-sighted. It's not as if game "journalism" has ever had much credibility. We predict it all fizzles into a he-said, she-said situation.
