I'd honestly be shocked if DCEU came out with more than two in 2019 considering what a disorganised mess they appear to be.
I mean folks say that, but is it really?
The only movie that has really suffered was The Flash.
The Batman never really had a date, and the only major shift (so faR) has been Affleck dropping as director.
Aquaman has been on point and so far nothing has gone wrong with Shazam?
Don't forget Teen Titans Go to the Movies!....I am still baffled how WB goes nearly an entire year without a single DC movie in 2018 till Aquaman at the end of the year.
