Back when we first found out that Batman will make an entrance in the DCEU, we still believed that the (then so called) Batman vs. Superman will be a Man of Steel sequel, with the Dark Knight having a minor role, just enough to make the fans aware of him in the DCEU. Then Zack Snyder made it clear that it isn't so and that it won’t be a sequel.
Later on, Henry Cavill announced that Superman is a pretty big (as in powerful) character, which means that it will take a while for him to have another solo movie. How much time? Well, at least until more powerful villains arrived on the stage.
Most recently, the rumor came out that the supposed Man of Steel sequel was indefinitely put on hold. Apparently, Warner Bros wants to focus on the Batman yet again "“ I don't have a problem with that (since Ben Affleck is a great actor), but I do have a problem with that (since this means that the studio has no idea of what to do with the shared universe).
It was just a rumor

Apparently, Man of Steel 2 being put on hold was just a rumor. After all, one of the most important superheroes of all times and a quintessential part of DC's Trinity, he should have at least a trilogy in the newly formed DCEU.
Of course, I say that mainly because this is the path chosen by Marvel "“ with solo films for the most important characters of its shared movie universe. But DC may choose another one "“ just like it did until now.
But, without digressing any further, it seems that Warner Bros is indeed planning for a Man of Steel sequel. And it will be one with Superman's most powerful foes. Who could they be? Check out on the next page!
