Im fine as long as we get a break from Wano in 2 chapters. What do you think, will this act continue till the end of Wano?(without any breaks)
Nah, but I dont think its ending next chapter. Give it a few more beyond that. Things are still technically ramping up. Fights haven't started anywhere else. People are missing entirely, the island is shifting us back to mainland.
Its like when Luffy fought Doffy. That started before any other type of fight, and it went on for some time before Oda dedicated like 12 chapters to other fights, then he returned to the main battle with Doffy.
Hes got a pretty particular structure, you can see this happening in Alabasta and Enies Lobby too. I expect this preliminary fight with Kaido to either cause the 5 Supernova to lose temporarily or least forced to change up their game.
Once that happens and the other battles are set up, then probably the act ends. Act 4 is maybe all fights and the Rocks/Kaido/Yamato flashback, plus whatever Orochi ends up doing if he's alive
