Because of the injury to star Dylan O'Brien, Fox had to move the release date for Maze Runner: The Death Cure to January 12, 2018 as production was shut down to give O'Brien time to recover. To go along with the shift, Fox released an updated film schedule which includes two untitled Marvel film projects.
The two 2018 films had been on the slate previously, but the first moved back from its original January 12th date to March 2nd and the second moved up from July 13th to June 29th. The first is most likely Deadpool 2 while the second could be anything from The New Mutants, X-Force to another X-Men film.
