I just found this: Looks like it will take them 3 years to push out the next one

Fantastic Beasts 3 looked set for release on November 20, 2020, continuing the pattern of the first film (November 2016) and its sequel (November 2018), but nothing had been confirmed.
However, it was then reported that production had been pushed back by Warner Bros from July 2019 to late autumn, while Warner Bros will now release Dune in that slot.
Star Dan Fogler said the change is because they needed "more time to prep" and since it was never officially scheduled for November 2020, it's not like the third movie has been delayed anyway.
And it's now been confirmed that Warner Bros will release the third movie on November 12, 2021, with filming due to start in spring 2020.
Warner Bros boss Kevin Tsujihara insists that they know how to make the movie better than the underwhelming Crimes of Grindelwald.
The fourth and fifth movies are yet to receive release dates, but don't expect them in 2022 and 2024.
