However, a new addition to the Marvel release schedule suggest this strategy may fly out the window in only a few years. Marvel StudiosAccording to Variety, Marvel has added an unidentified Marvel film to its release schedule for December 15, 2028. 2028 is planning way far ahead, even for Marvel standards, but there are actually already three other Marvel movies planned for release in 2028. It’s possible, even likely, that this won’t be what the release schedule looks like by the time 2028 rolls around. Marvel may be betting its upcoming Avengers movies will usher in a new golden age.
