Warner Bros. has officially scheduled a full slate of DC Comics films, which will be released between 2016 and 2020. In addition to two Justice League movies, the plan also includes solo outings for everyone from Wonder Woman to Cyborg. The studio has stated that they intend to release a standalone Batman film and a proper sequel to Zack Snyder's Man of Steel Henry Cavill's Superman within the next five years.
Excitement for the next Kal-El solo outing increased exponentially when the rumored emerged that Mad Max: Fury Road helmsman George Miller is lining up to direct Man of Steel 2. However, if a new report is to be believed, that project may not be moving forward in the immediate future.
Den of Geek is reporting that while WB remains interested in bringing Miller on board to make a DC film, which film he would make remains up in the air - as Miller will (presumably) take whichever film interests him the most. Meanwhile, the proposed Man of Steel 2 is said to be on "permanent hold," though Den of Geek's sources didn't elaborate beyond that.
It could be that Man of Steel 2 is just not a priority for WB/DC right now; after all, they still have a lot of marketing to do for the 2016 releases Batman V Superman: Dawn of Justice and Suicide Squad, at the same time that Wonder Woman and Justice League Part One will enter production. Man of Steel 2 isn't expected to reach theaters any earlier than 2018, so it may simply be on the back-burner right now.
If accurate, this doesn't mean Man of Steel 2 is off the schedule completely; the first Man of Steel is quite divisive with critics and audiences, but was still successful enough at the box office - $668 million worldwide - to serve as the launching point for the DC Extended Universe. Plus, Superman is one of the studio's most marketable characters and remains popular with the masses, so the audience is there for another solo movie with Kal-El (much like his Justice League colleagues will all get their own vehicles in time).
That Man of Steel 2 is described as being on "hold" and not "canceled" also signals that WB still plans to make the film (eventually). The biggest roadblock at this juncture is probably scheduling and logistics; WB is releasing two DC films per year, and that's without including either Man of Steel 2 or Ben Affleck's Batman solo film. Kal-El may be taking a backseat to other DC superheroes for now, but there's little reason to think he won't get the spotlight to himself down the line.
Batman V Superman: Dawn of Justice opens on March 25th, 2016; Suicide Squad on August 5th, 2016; Wonder Woman on June 23rd, 2017; Justice League on November 17th, 2017; The Flash on March 23rd, 2018; Aquaman on July 27th, 2018; Shazam on April 5th, 2019; Justice League 2 on June 14th, 2019; Cyborg on April 3rd, 2020; Green Lantern Corps on June 19th, 2020. Dates for the untitled Batman solo movie and Man of Steel 2 have yet to be announced.
