According to the story, the plot in the script written by Christopher McQuarrie involves Logan beginning a "forbidden romance with a Japanese woman whose hand in marriage is, unfortunately, promised to another man." Since Logan won’t take "no" for an answer, it puts him into battle with her father and her "samurai-sword-wielding brothers." We fully expect the Silver Samurai to be one of those brothers. His father is Lord Shingen Yashida, a Yakuza crime boss and a mutant himself. One can also expect the movie to deal with Wolverine’s relationship with his daughter Mariko Yashida, and who knows, maybe we’ll even see Yukio in the new movie, but that’s a lot of Japanese (or Asian) actors who should start lining up for roles in the movie if they’re going in this direction.
A release date has not yet been set for the sequel.
