And even if this DLC isn't the "Big SI-esque" one we've been waiting for(Despite them having a year to work on it) perhaps that just means we'll get a third DLC down the line.
Yeah, I am still hoping and expecting 1 big SI expansion pack. Skyrim is too good of a game and too successful to not give it a full expac. So very few games can even afford to risk making an expansion pack, but Skyrim is a guaranteed thing, so it is a great opportunity to do something most devs/publishers can't risk doing.
