Upcoming Marvel films include "Black Widow" (2020), "The Eternals" (2020), "Shang-Chi" (2021), "Black Panther 2" (2021), and "Doctor Strange 2" (2021).
Any one of these is a possible contender for the panel, as well as rumors of a possible gathering of the "Orginal Six" Avengers to say a last farewell. Avengers banners are already decorating the streets around the San Diego Convention Center. While it would be a unique move to highlight a past series of films, one can't forget the huge role that all of these actors played in awakening this iteration of the MCU and after all these years, a proper send-off would seem a welcome event.
San Diego Comic-Con will take place from July 18-21.
