I think we're going to see background progress for all the main fights. We should get to see where Momonosuke and Shinobu end up landing and if they run into anyone.
Denjiro, Izo, and Kawamatsu are yet to find their opponents.
Ulti and Page One should eventually recover. Mainly Ulti since that's who Nami declared she'll crush and because she just got Zeus back.
Law's crew found Luffy, but now it's time to save him.
Kaido and Yamato will continue their dialogue and potentially even fight.
