MMO Champ wouldn't open this new section if this was still speculation. They know that this is the name of the expansion so they did this. There never was a "Dark Below" sub section here. Bibi also gets NDA informations he can't post here. But right now he knows exactly what the next expansion is all about. It's easier to give big Websites the informations first AND force them to NDA this information. That way they can control leaks better than hoping nobody talks.
