Who said that? Who said that just this week on their weirdly popular podcast? That From Software was gonna' step away from the Dark Souls series and make a new thing? Oh right it was me!
The cool peeps over at NeoGAF translated a Chinese-language interview with (series creator) Hidetaka Miyazaki, and there's two interesting things. First off, there will be two pieces of DLC for Dark Souls III - one coming Fall 2016, and another coming Spring 2017.
Second, and more importantly, the studio is stepping back from Dark Souls to create a new IP:
"...if a FROM Software developer come to me five years from now and beg ‘please let me make another Dark Souls‘. Then I will not rule out the possibility to let my subordinates start a new project.Please something set in Japan with all kinds of Shinto spirits. I wanna' fight a nine-tailed fox with nothin' but a katana and some skill in a From Software game.
What is certain for now is, to me personally Dark Souls is over. So rather than make another sequel, I think it’s time we take a step to a new direction. Development of a new IP has already begun."
