Then Gringotts - who knows what will they make out of that, you can't expect them to show the goblin's questioning, the tunnel and their search for cup as half of the movie
riding the dragon - that won't last more than 2 minutes
that big moment when the goblin tells Voldemort about the stolen cup - like they're going to make it such a big moment
hanging with Aberforth - i'd rather think they will skip the whole "Dumbledore's family" story.. what difference does it make if they do?
Grindelwald flashbacks - they also have no reason to mention Grindelwald
