@Deadlysyns87: It's what people read. When a major game is released, people crave information on it, and you would be surprised to learn that the GameSpot commentariat does not represent players at large. As with most games-related publications, most of our traffic comes from Google search and, to a lesser extent, the front page of our own website, and Witcher 3 information is what they are searching for. We have detailed data--like most websites--about what people search, how they click, how long they stay on a page, etc etc etc. That data helps us learn what people read and watch.
This shouldn't be a surprise to anyone on the Internet, really. When there's an episode of Game of Thrones, or the Mad Men final comes, or an Avenger film is released, or whatever, websites publish things about it because there is a large audience for it. When something else happens--a new game is released, or another big film comes out, or something else big happens in a given medium, the conversation shifts. That is how we draw traffic and make money, so that we can do other articles when there isn't lots of news on a major game, and review games that don't have 500-member development teams.
