I really hope that Luffy (perhaps with Kidd and Killer) will reach the top of the dome where there are Kaido and BM and then Kaido after reaching the flower capital will drop the island.
I rally hope for this, because counting the pacing of the actions, of the last chapters this would be too fast, infact the pacing is very slow.
Actually even if I would be really happy if Kaido will drop the island on the capital I believe that he will not be able to drop the island, even if we would see the reactions of Wano's citizens when they will see Onigashima island in the sky.
As someone already mentioned I believe Oda will need few chapters to end the Act 3, because Page One and Ulti will reach Nami and Usopp.
Just like it has been hinted in this chapter Zoro and Marco will fight Queen and King, until Sanji will be able to escape from Black Maria (after Robin will reach them and will take Sanji place in the fight) and then He will fight Queen while Zoro will deal with King (I believe this because in every arcs Zoro fought the second strongest while Sanji the third strongest even because King is a tengu, and in Japan the tengu carry a sword and are very strong with it).
Franky as already happend will fight Sasaki while I think that Brook will take Jimbei's place in the fight with Who's Who, most likely after than Jimbei will take out Who's Who mask. I believe this because I think that Jimbei will fight Jack, since in the meantime will be back in action.
After that X Drake changed size, one Strawhat will not be able to fight a member of Kaido's army, most likely Chopper, He could just create a counterpoison or others enemy, like the Numbers or BM soldier.
Sorry if I made some mistakes but the english is not my first language.
