Little lost here?

So I just rewatched all the Harry Potter movies and now I doing it with the Fantastic Beasts.

I have not watched the 20-year anniversary film and I do not plan to, because it is not a actual film of the story, but more about the actors.

But I kinda feel lost about the future because I keep seeing random posts as the trio as grown ups at Hogwarts, so is another film or series in the making that I can not find?

Thank you fellow wizards and witches
