Dark Souls and Bloodborne developer From Software has announced a brand new game called Sekiro: Shadows Die Twice. It's published by Activision, notably, and is coming early 2019 for PC, PS4 and Xbox One.
Sekiro: Shadows Die Twice is directed by From Software's top dog, Hidetaka Miyazaki. It's Sengoku Japan and ninja themed, and casts you as Sekiro, the one-armed wolf - presumably a reference to one of his arms being skeletal.
Tonally it gives off strong Bloodborne vibes (Miyazaki directed Bloodborne). The world is dark and twisted, and enemies grotesque, and the style of fighting seems to lean towards aggression rather than caution, as in Souls.
