User blog comment:Jimeee/Hearthfire confirmed as the latest add-on. Official trailer./@comment-1992639-20120829110921

It's a bit like I predicted half a year ago though. First a big DLC with lore expansion, then a smaller DLC to add gimmicky content that's fun to play with as a means to keep people occupied. I'm guessing the next DLC is either quite large again, or we get another 'snack' (around christmas?) before something bigger is released, while after that we get a play-thing again, in the range of a new item set, putting your family weapon on a cape, combat pets, that sort of stuff.
