The only one of those that currently has any major competition on it is the November date, as that’s when Disney’s live-action Mulan is currently set to debut.
Still, with the movie slated to go into production shortly, we can expect Deadpool 2 is set for sometime in 2018.
Fox currently has three dates set aside for Marvel films next year which are March 2, June 29, and November 2.
At this point, the June date would seem to be the most likely if filming is set to begin in a couple of months.
