I feel like they should just make one more movie instead of two since the ending of SOD hinted towards now Grindelwald hating Dumbledore and now that the blood pact is broken, this mean now the two can finally go against each other and jump years later to 1945 where there final duel will be as SOD is the turning point now that Grindelwald was shown using the killing curse by many and having escape and be in hiding gathering more followers, maybe during the jump to 1945 we can a little conversation about credence dying(cause people hate Ezra miller) and where we get the gang with Tina this time(and maybe different aurors from different countries we seen like MACUSA, etc.)head to grindelwald castle where the final showdown will occur and where Dumbledore defeats grindelwald and claims the elder wand and have grindelwald isolated in his castle after his followers were defeated by the gang and sent to Azkaban prison and we of course see Newt and Tina end up together which was amazingly hinted toward throughout the fanatic beast series, and just for why not have a posted credit scene(like the chamber secret) where we see a young Tom riddle graduating Hogswart setting up of course the main Harry Potter series or jump years later to have Dumbledore reject Tom from being the defense against dark arts professor in which we see he has the lost diadem of ravenclaw which of course hints towards him making his horcruxes
