Well, it seems remaining plots are:
- Show adult Momonosuke finally, and his speech as Shogun, and his meeting with her sister Hiyori.
- Update on remaining Scabbards, Kin'emon (meeting his wife), Kikunojo, Izo and Adhura Douji. We need to see who died and who was only highly wounded.
- Zoro getting up and talking to Tenguyama Hitetsu (maybe he will reveal as Kozuki Sukiyaki too, and the musterious Kokeshi dolls) and Onimaru. More info about Ryuuma, swords and probably more Shimotsuki Yasuinand Ushimaru.
- Marco, Izo (if he gets up and it's not reslly dead) and Jinbe telling us interesting things.
- Zuneesha and World Government stuff. Will they land now on Wano, call for back up Marines/Buster Call, will retreat or will they be sunk?
- CP0 who escaped informs the Gorosei directly, or he talks to Rob Lucci or someone on the ships at Wano borders.
- Wano Phoneglyph.
- X Drake and Basil Hawkins status.
- Maha and CP0 "boss" status.
- Apoo escaping and sells Morgans the new information.
- Caribou's true intentions, and probably his boss finally revealed.
- Yamato reveals to Wano citizens and probably they will go mad for a while until Luffy, Momonosuke and maybe the Scabbards tell them she's not an enemy.
- Oden's journal maybe finally read properly.
- Maybe another party.
- Act III ends or directly Wano arc ends giving us our revelations about the outside.
I think I have nothing more left here.
So, how many chapters, my dudes?
