It's really telling how Atlus is sleeping on anime projects/adaptions when JJK, Chainsaw Man, Yaiba and Dandadan are super popular right now.
They could... I don't know, make some anime adaption of the spin-offs or a movie for Epsiode Aigis (formerly known as The Answer) or the Royal content.
Not that the anime adaptions where very good, but the original P4 anime was very decent and a good side-content.
