This is out in June right? If it's true, still got a lot of time to edit/cut/chop the movie - you just have to hope they don't need to re-shoot things haha - pretty sure that's what happened with Suicide Squad.
That's what I thought, surely there wouldn't be a finished cut with 5 months to go right? Interesting if so. Although this is usually the time where WB steps in to meddle with the movie and commence reshoots etc.
