Speculations Zoro is not gettin a big bounty after this arc

Doesn't cpo no everything most likely they been watch from a distance because they seem to no alot plus they have that girl with the eye ability, so if they saw the whole fight zoro should get a 1.1billion maybe more
he is not gettin 1,5 B+ for wounding kaidou when no marine saw the roof battle, unless he 1vs1 king.
he will get at most 800m - 1 Bilion.

and also means sanji is at best beating someone like perospero to get 700m, not calamity
Once again Wano is not over. Zoro will kill Kaido by the time it is done.

Zoro will fight and beat King. Beating King and killing Kaido will increase his bounty.
