If you want to expose a DLC at E3, it must be good... of this I am sure.
What do you think?
I said as much about half a dozen pages back, though I wouldn't brand it as "I'm sure", because, well... Bethesda Softworks (Publisher) is kind-of a one-trick pony with The Elder Scrolls series. Even with a juggernaut of fame like ID behind them now, Dishonored and any ID project are arguably second-serving to anything Bethesda Game Studios cooks up, so if they need a commanding presence at E3, anything Skyrim-related will do the trick.
I don't recall any instance of DLC or Expansions for BGS games going to the show though, but I didn't make a day out of researching that.
