There may be post-release content after all
It was admirable of From Software to treat Dark Souls II as "a full game," in the words of producer Takeshi Miyazoe, and not plan for DLC as a required part of production. I don't think any of us are expecting anything less from the studio. That said, after Artorias of the Abyss turned out the way it did, I wouldn't mind DLC for the sequel. Not at all.
Talking with OXM, Miyazoe has since expressed more of an openness to the concept, saying "There is definitely potential, I think. Again, it's all about fan feedback. Right now we are concentrating on completing what we've got, but I think there are next steps on how we can expand on Dark Souls II. So I'm not really ready to say look forward to more information, but I think the potential is definitely there."
So, yes -- count me as a fan who would like more Dark Souls content.
