So Wano gonna end sooner than expected
Potentially. Depends on two things
-getting back to a ~39 chapter year without COVID getting in the way
-the first fight with a Flying Six concludes in the next ten chapters
If Oda does what heโs done in Alabasta, EL and Dressrosa- the arcs most like Wano in structure- then the final fighting part of the arc will take ~30 odd chapters to finish.
The five TR will get either a one or two chapters purely devoted to their fight. (5 or ten chapters)
Then the Calamities will get two chapters. (6 chapters)
Then Kaido will get about ten chapters once everyone else is down
