The MCU just announced some huge changes.
Disney also announced a few other changes. Including the removal of two untitled Marvel movies.
Finally, two upcoming MCU films, Spider-Man: No Way Home and Guardians of the Galaxy vol. 3 are staying put at December 17, 2021 and May 5, 2023, respectively.
(Eternals is also still releasing in November, and as far as we can tell this shouldn’t impact Marvel’s Disney+ plans.)
