Jin Sakai will join Master Chief as the next super-bland gaming character to get an adaption for the silver screen. The good thing about this is that you can't screw up Jin, because any actor with the ability to do his job, will fill the blank canvas that the original character left behind. That's not a knock on Ghost of Tsushima getting a movie, though, because I love the idea. Also, Samurai movies have historically worked well with silent protagonists, so this one has all the potential in the world.
Ghost of Tsushima Movie by John Wick Creator
This potential is especially amplified by the fact that John Wick director Chad Stahelski is helming the project. John Wick is a franchise that's all about a simple, effective story, a silent protagonist, and beautiful combat choreography and visuals. That's literally perfect for Ghost of Tsushima because that's literally what Ghost of Tsushima is.
Stahelski has also revealed that he's working very closely with the devs, and the story will be a faithful retelling of Jin Sakai fighting off the Mongol Invasion as the Ghost of Tsushima. Honestly, I've always thought that Ghost of Tsushima is just Batman Begins in a different setting, so I'm expecting something very similar here.
There is no release date as of now, and the director has simply stated that they are going to be taking their time, so I'm assuming we can expect a release date around the time that Ghost of Tsushima 2 becomes relevant - simply to capitalize on the hype.
