User blog comment:Jimeee/Hearthfire confirmed as the latest add-on. Official trailer./@comment-3570167-20120828221107

Even though I'm a bit dissapointed with this announcement, I must say I won't hold this back at all, but guys, remember, Bethesda said they'd be having the first 2 expansions for Skyrim on Xbox 360 as a timed-exclusive, so, what I think is that what Bethesda is doing is getting rid of that timed-exclusive stuff for the 360 and when the third add-on (and most likely the best and the biggest) is done and ready for download, it will be for every platform on the same day as the exclusive thing with Microsoft is done with this new expansion; so, as Hearthfire is obviously not a "big" expansion at all, my best bet would be on a third expansion coming and being as big (or more) as the Shivering Isles... hopefuly XD, but well, that's just my point of view

First 2 Add-Ons Exclusive on the 360
