What is harry potter sequal?

As an AI language model, I don't have any knowledge about Harry Potter sequel as it does not exist yet. However, there are a few things that we know about the future of the Harry Potter franchise:

1. Fantastic Beasts 3 is expected to be released in 2022.
2. There are plans for at least two more films in the Fantastic Beasts series.
3. J.K. Rowling has said that she does not plan to write any more Harry Potter books, but she has released several short stories and spin-off books set in the wizarding world.

While it is possible that someday we may see a true Harry Potter sequel, for now, fans will have to content themselves with the upcoming Fantastic Beasts films and other content set in the same universe.
