wait 20+ more chapters. not even joking
Lol yup people are underestimating these fights.
I give it another 3-5 chapters before everything is even "solidified" in terms of who is fighting who. Then even at that point, who knows how long it'll take for Oda to start drawing the 1v1 chapters dedicated to making the villains fall.
Only then will you get the 15-20 chapter Kaido fight.
Hell, we may even get an act break soon, nor do we even know where the story is going with Orochi, Onigashima, and the rest of the main Wano inhabitants (Hiyori/Tengu/Onimaru/Hotei/Fukurokuju) or Yamato will encounter Kaido and have a moment or if Momo will meet Orochi.
So many factors
