won't happen, because zoro is fighting lucci so if sanji were to fight saturn that would mean that lucci is stronger than saturn and that can't be
Vegapunk,Atlas, Franky and Sanji will meet Bonney
Jinbe will also show up a little bit later
Sanji, Jinbe and Frany vs 3 VA's
Kuma will show up. Bonney and Vega will run into him and Saturn will also show up
We will see Kuma's backstory and learn something about his race
 
Kizaru/Luffy fight is boring
Both seem like they don't care

Forced fight to showcase Luffy's growth.
I do not think this will be a full fight nor will it have a conclusive victor

Luffy wanted revenge against Sentomaru, Pacifista, Kizaru
Saved Sentomaru, offscreened Seraphim, lackluster Admiral fight will be stopped by Gorosei/Iron Giant
