The Batman has been pushed back to to October 1st, 2021, after an original release date of July 25, 2021.

Now we have some plot points for the movie. First, Matt Reeves said this about the movie to the Hollywood Reporter:

It’s very much a point of view-driven, noir Batman tale. It’s told very squarely on his shoulders, and I hope it’s going to be a story that will be thrilling but also emotional. It’s more Batman in his detective mode than we’ve seen in the films. The comics have a history of that. He’s supposed to be the world’s greatest detective, and that’s not necessarily been a part of what the movies have been. I’d love this to be one where when we go on that journey of tracking down the criminals and trying to solve a crime, it’s going to allow his character to have an arc so that he can go through a transformation.

So what is going to happen in the movie? Well, there could be spoilers ahead, so scroll with caution. But here is a synopsis:

The movie takes place in present day and it's a young Bruce Wayne, very close to the version in Frank Miller's Batman: Year One. It's election time in Gotham City and the candidates for are being murdered, with riddles being left at the crime scenes. That would lead right into Paul Dano playing the Riddler.

The movie is said to be very much with a noir theme, borrowing a lot from Sherlock Holmes, with Batman truly being a detective.

You also have Colin Farrell playing a character named "Os", which would be short for Oswald Cobblepot, AKA The Penguin. And Zoe Kravitz' version of Catwoman is the true anti-hero, as she does help Batman out, but ultimately is looking out for herself.
