During a recent interview with 4Gamer.net From Software President, Hidetaka Miyazaki, (or as he's knows by the Soulsborne fanbase, Lord Miyazaki) confirmed that the studio is currently working on two unannounced titles.
During the interview Miyazaki explains that there have been 3.5 lines of development at the studio in motion since 2016.
0.5 is Déraciné, 1.0 is SEKIRO, and the remaining 2.0 is an unpublished title.
Miyazaki also went on to say that both Dark Souls Remastered and Metal Wolf Chaos XD can be excluded since they were requested from outside the studio.
When asked if he meant that the studio currently had two unanounnced titles in development Miyazaki confirmed that to be the case. He said that now is not the time to talk about details, but that both of these titles will be in line with previous From Software games.
There is obviously lots of speculation going around right now about what these two titles could be, but I think a lot of people, myself included, are hoping that one of these are Bloodborne II and the other Demon's Souls Remastered. As a huge fan Bloodborne, I have been waiting for a sequel ever since I finished the game and obtained the platinum trophy. While From has shown that they can do wonders when they are working on a new IP instead of a sequel I still want more Bloodborne. In the same interview Miyazaki does also mention that the recent Blooborne easter eggs in the studio's VR game Déraciné were just a little mischief by the studio, having a passion for Blooborne themselves, and that they might have gone too far with it.
Some time ago it was also reported that From are working on another title in the Armored Core series. Nothing was confirmed and I haven't seen any new information on it recently, but it's entirely possible that one of these titles could in fact be a new Armored Core. I'm not a fan of the series myself, but thinking about an Armored Core game that plays like a Souls game has me very intrigued.
Regardless of what either of these titles are I'm sure Lord Miyazaki and his team at From Soft will deliver the goods. We can only look forward to more information regarding these titles.
