I love all the comments saying "I'm 100% sure it's a D3 expansion." Based on what, exactly? Three words, it's nothing but three words. To me, the only evidence pointing any direction in this thread is the references to the "dark below" in the context of the Warcraft universe. The only tie to anything D3 related would be because we're so close to a presumed D3 announcement at Gamescom... but of course, if you read earlier in this thread, you'll see the argument against the wisdom of waiting 9 days before an announcement to register a trademark....
