Eventually when the time is right he'll come back out of the wheelhouse classic '90's cartoon character many of us remember. It shouldn't be rushed though.
What to Do with Fox Film Lineup: Many fans complained about the Fox films being too Wolverine-Centric. Fox has already made X-films for next yr so might as well profit from something already made than throw it in the trash for no one to see without meddling with them in any way (don't need endless speculation like happened with Justice League).
From there, James Mangold film, X-Force, and Gambit can be lined up for 2019 and 2020 under R-Rated line of movies letting fans decide if want consider loosely connected or not. The Dark Phoenix movie coming out next yr presents the most difficult resolution so I think they should wait to see how it's recieved and decide on a sequel or not end of next yr. If a sequel, then will have to mesh with MCU while if not then can have a total reboot. With re-boot, I think that should happen post-2020.
Wolverine Solo: Wolverine solo in MCU also post-2020 after focusing on X-Men first. X-23 could continue off of Logan and be something apart from MCU like Venom is from Spiderman if Marvel going to have an R-rated line maybe if a Fox studio still exists under the Disney umbrella for the interim.
