Before kaido falls there are still 3 major subplots that need to be resolved
- Big Mom vs Kid and Law
- the Kurozumi subplot
- the Kazenbo
- Raizo vs Fukurukujo
- Orochi vs Hiyori
- Apoo and Drake vs CP0
Apoo and Drake's fights as well as Raizo vs Fukurukujo can be mostly off-screened. However we need to see their conclusions. Also Kid and Law vs Big Mom needs at least 2 chapters, even if they lose. Orochi vs Hiyori needs at least one chapter if not more. The kazenbo also deserves a chapter.
Also, I wouldn't rule out the possibility of Usopp vs Zangi and Inbi.
