Dark Souls can't change that much. It can't completely rewrite the rules of what it means to be a Souls game, or at least it's not willing to do so. Each new Souls game reshuffles the deck, but you're still playing with the same 52 cards. And for a game that's built on needing to "solve" its systems, that's a problem--if not for you personally, then for the absolute diehards at the core of the community.
To be clear: I don't think Dark Souls III is a bad game. In fact, I'm sure I'm going to enjoy it until I inevitably plateau. It's got the same brooding atmosphere, the same creative monster design that I fell in love with the first time around. To me, "It's more Dark Souls" isn't a bad thing.
But those who bought into the series because it was difficult and awkward and new, those looking for a real challenge or at least a "new" challenge, I think will have to wait and see what From Software and Hidetaka Miyazaki do next. Hopefully something Bloodborne-esque, something that rewrites the rules again (and not PS4-exclusive). Dark Souls III feels familiar, and for this series--and some of its core fans--that's not necessarily a good thing.
