Yes, they are different time periods but they deal with the same subject matter. Basically ronin samurai, open world, sword and stealth combat. Ghost of Tsushima came out in 2020, i would say late 2024 is most likely and if its 2025 it will still be coming out under a year of Ronin. This is also the Year Assassins Creed Red is set to come out, so we may very well get 3 big samurai/ninja games in the span of a year. Kind of feel like Sony is stepping on their own studios toes working on another game with a similar setting and theme.
Sort of like they did for Days Gone after The Last of Us came out.
