Inhumans, set for a July 12, 2019 premiere, has now been taken off Disney's schedule altogether, confirming what fans had heard about two weeks ago.
Deadline reported the un-scheduling, but noted that this is not a cancellation; Marvel just has to figure out when it wants to premiere the movie. It appears to have been shuffled out of the Disney deck by the Indiana Jones film that was announced back in March for a July 19, 2019 premiere.
When it was first announced in October 2014, Inhumans was given a 2018 premiere date that was later moved to 2019. Since October, Marvel has also announced Ant-Man and the Wasp for 2018 and revealed Spider-Man: Homecoming, giving the reboot a July 7, 2017 launch date.
