At the end of the X-Men Days of Future Past movie they are pulling Wolverine out of the river. I believe Mystique was pretending to be Stryker and was going to take him somewhere. Maybe she is taking Stryker's place and going to take Wolverine to the storyline where he becomes Weapon X and then gets his adamantium claws.
Or it could be as simple as Jackman not being available for the movie and they didn't want to replace him. I do think he has only one more movie under contract and that is another Wolverine movie.
No wolverine?
Thanks. He was born for that role. It's going to be a sad day when he leaves the franchise. I don't foresee anyone that can replace him.
