Wolverine is one of the most iconic characters in not only the X-Men franchise, but in all of Marvel. Therefore, it is only expected that people who are involved in the Marvel franchise is going to want to use him for their projects. The Russo brothers have recently stated that they had wanted Wolverine for Infinity War. One interesting thing was there was some point when Hugh Jackman has talked about playing Wolverine in projects after Logan. However, he has ultimately decided not to. For one thing, he knows he is aging and for this reason among other reasons, he has decided that he is ready to pass the torch.
Fans have speculated that Wolverine was going to make an appearance in either Avengers: Infinity War, or Avengers 4. There have been many speculations as to whether or not he is going to use his outfit that was seen in comics and other media, but only glimpse at on film in a deleted scene. Fox is still working out everything with Disney and everything is expected to be complete by 2019. This is when people can expect some other iconic characters in the MCU to pick up where some of the current set of characters are going to leave off.
Given that Wolverine has died in the most recent film, Logan, it is probably a good idea to let him rest and perhaps focus on some of the other characters in the X-Men franchise. In most of the X-Men movies, Wolverine was given most of the attention with all of the other characters besides Xavier taking a backseat. The First Class movies does give some attention to other characters. It is highly likely that all of the X-Men characters are going to be done justice in the MCU.
