Duel between Dumbledore and Grindelwald in Fantastic Beasts

Hello everyone

how do you picture the duel between Dumbledore and Grindelwald in probably the last movie of Fantastic Beasts? It is said to be the greatest duel of all time, how will they show it on screen? I was a little disappointed in Dumbledore vs Voldemort in OOTP annd hope it will be a lot more spectacular
