Warner Bros. has announced that Shazam! will be released on April 5, 2019, confirming that the date, which was previously filled with an unnamed DC Comics film project, belongs to the Zachary Levi starring film, according to Deadline.
Likewise, Deadline reports that the untitled DC Films project scheduled for a July 27, 2018 release date has been removed from Warner's schedule, but only sort of.
Warner Bros. Animation's Teen Titans Go! To The Movies is currently scheduled for that date.
