So I'm gonna give out possibilities on what's gonna happen based on the rumours, talks and reaction from different sources.
The less likely possibilities :-
1) Hiyori and Orochi situation
2) Something to do with Scabbards
3) Zunesha attacking WG ships
4) Zoro waking up
5) Named characters dying (Not happening but let's cope)
The more likely possibilities :-
1) Kaidou going rampage
2) Someone kind of Kaidou Flashback
3) Momo Luffy talk maybe?
4) We might get another Gorosei's talking panel while they talk bout the fruit
5) Luffy confronts Kaidou at the end of the chapter
