The team would be hard at work at creating meaty quest-based mini-expansions at this point. If you're after official horse armour-esque DLC (eg stupid **** like premium weapons and clothing packs) then you're playing the wrong game.
"For Fallout 3 we did five DLCs," Howard told me during an interview last week at the DICE Summit. "That was a very aggressive path for us. Our plan now is to take more time, to have more meat on them [for Skyrim]. They'll feel closer to an expansion pack."
In between those expansions, Howard is committed to releasing smaller pieces of content for the game.
"Because that gap is going to be bigger, we want to put litle things out for free in between. We've already done that for PC with the high-res pack. We're trying to figure out what those things are."
