"Since we made our initial phase three announcement, we added 'Spider-Man,' which was a big joyous coup for us. We added 'Ant-Man and the Wasp,' which was a big fun continuation of that story for us. Walt Disney Company has announced an 'Indiana Jones' film for right around that same time. So I think ['Inhumans'] will shuffle off the current date that it's on right now. How far down it shuffles, I'm not sure yet," Feige explained to Collider.
Regardless, "Inhumans" most certainly remains on Marvel's agenda. "It's a question of when," he added.
Due to the addition of films like "Spider-Man" and "Ant-Man and the Wasp," previously announced movies like "Captain Marvel" and "Black Panther" have shifted in order to accommodate them. As such, it isn't surprising to see "Inhumans" get the same treatment, though it's unclear at this time when the film's new release date will be announced or when it will premiere.
"Inhumans" was originally scheduled to premiere on July 12, 2019.
