I know this may be a daunting task, looking at the huge list of companies, but still, someone needs to update them. There shouldn't be any outdated information on this site unless it's in the news archives. I mean, your Silicon Knights profile says that Eternal Darkness "might" come out on Gamecube, according to rumors....That's like, from before the GCN launch....
Unfortunately, IGN commited the same crime. Don't make a section of the site and forget about it! If it's there on the main menu, people will be going there....
