Even discounting review score bombing by trolls, that's still ludicrously low. I don't think anyone is surprised review sites rushed to judgment and I think the backpedaling is pretty obvious. The excuse that they published their review specifically about the controlled review experience is really stupid, people don't want your impressions of a controlled environment. They want a real world idea of how the product is going to perform.
I don't think anyone expects honesty out of the gaming press anymore though, EAs adbux simply command too much power in the industry.
