This Saturday's event has been rebranded "DC Fandome: Hall of Heroes" and will only feature the movie panels, plus The CW's The Flash, DC Universe's Titans and the Montreal and Rocksteady videogames.

Everything else, including the rest of the television properties, has been shuffled to "DC Fandome: Explore the Multiverse" on September 12, which will be an on-demand experience where you set up your own schedule. Also, the secret panel that many assumed would be a new movie announcement has been cancelled entirely.
