Interesting.
2013 - Man of Steel, Arrow (separate TV universe, hereby the Arrowverse)
2014 - Flash (Arrow-verse)
2015 - Superman vs Batman
Here, we delve into an established Batman and escalate things with Superman and we introduce a lot of different little bits about this DC universe, especially Wonder Woman, but with threads about Green Lantern, Cyborg and others that will be picked up later.
Fall 2016 - Wonder Woman
This is actually not a tentpole summer film, but a lower budget drama that fills in a lot of the past of the DC cinematic universe, like what CATFA did for the MCU. We also flesh out Gadot's character and see the passing of the old gods for the New Gods.
2017 - Justice League: Secret Origins
Here, we have a fairly straightforward first Justice League film that sets up Darkseid as the overarching enemy but has them whomp on an alien invasion that involves Despero, The White Martians and Starro. The Anti-Life Equation is obtained and it becomes the heroes' job to protect it from Darkseid. They key twist: The entire Justice League trilogy has been filmed at once. As such, this is not an introduction to a set of characters so much as a world, a very four-color inspired world, albeit, with muted tones. A world where superheroes are almost common, where there's been an explosion of super science.
Winter 2017 - DC movie starring The Rock that spins directly out of and ties directly into the Justice League trilogy.
2018 - Justice League: Crisis on Infinite Earths
Here we play or all the marbles, and we do our huge team up, not just with the Justice League we met last year, but since we're dealing with multiple dimensions, we can have the Arrow-verse characters involved saving the universe now. We can have Bale's Bruce Wayne or even JGL's Batman in full effect with Michael Keaton's aged Bruce Wayne in the shadows or better yet, Kevin Conroy as a live action aged Bruce Wayne! We can even bring back Tom Welling AND Dean Cain's Superman to stand alongside Henry Cavill. We can simply pwn. Heck at this rate, even Ryan Reynolds can get a cameo. The story would be epic, sprawling in pockets in strange connected ways, like Crash or something, all leading up to someone dying. Leverage DC's incredible history on film into something peerless. Something unprecedented. An unforgetable movie experience.
2019 - Justice League: Final War
With that done, it's time to bring home why exactly the DC universe is the original. Deeper character moments and truly engaging villains and an irrefutable message of hope in the darkness. Let us see Darkseid in all his glory as the brilliant character he is. Let us get to the heart of what makes these characters sing, when everyone dies, Batman included, when it's just Superman and a wish, what happens.
2020 - The Green Lantern Corps
A full space sci-fi epic.
Fall 2020 - Gotham Knight
Batman is back in his own feature with some kind of Bat-family thing going on.
2021-2028: Solo features, having a big summer tentpole every year, and rotating who that is, then backing that up with one or two supporting lower-budgeted non-tentpoles each year. Leave Batman as a sort of yearly franchise, almost James Bond like that focuses on gritty noir story, and not on spectacle. Superman and Green Lantern is your big spectacle, while Wonder Woman is more of a girl-power kick-butt thing.
2030-2033: Every 5-10 years do another Justice League trilogy. Next time, base it on Forever Evil and the Crime Syndicate and Justice and the cool stories that have popped up about those themes since then.
2033+: Repeat.
