I just wanted to point this article out. Really!? Finish Dawnguard first bethesda.
Article is based purely on conjecture, but there's been a few published recently which makes me wonder if the wheels are turning on Hearthfire while over two million Skyrim owners continue to wait for just news on whether they will receive Dawnguard.
Bear in mind also that Hearthfire is 30 day exclusive to 360 as well, so if they are working on a new DLC at the expense of Dawnguard then we may as well give up on receiving DLC at all as we're clearly not even on the "to do list" let alone the priority Bethesda claimed last month when Dawnguard released for PC but not PS3.
