Only now, there might be.
Dark Souls 2 producer Takeshi Miyazoe had a chat with Official Xbox Magazine recently and it appears that things may have changed.
“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 2. Whether or not such steps would be taken, would depend on fan feedback. “I’m not really ready to say look forward to more information, but I think the potential is definitely there.”
Not conclusive, sure, but it definitely creates some food for thought. We’re going to assume that as long as the game sells well and people want more content, we’ll be getting some form of Dark Souls 2 DLC in the future.
Unless things change again..
