Marvel Studios can tell one major Iron Man story during their upcoming Armor Wars film. Armor Wars was officially announced to be in development at Disney's 2020 Investor Day, initially being penned as a six-part Disney+ series, but it was later revealed that the project would be reworked into a feature-length film. Armor Wars will see Don Cheadle suit up as War Machine, leading on from his upcoming appearance in Secret Invasion alongside Samuel L. Jackson's Nick Fury. While the film will deal directly with Tony Stark's death in Avengers: Endgame, Armor Wars has the opportunity to tell Iron Man stories that the MCU has previously avoided.
