Yeah, it seems as if I spoke too soon for ZKK
if Zoro vs King really does parallel to the ryuma, then imo that would reduce the chances of ZKK happening. The chapter does seem much more impactful in the summary than in the quick synopsis.
However, I think I'll choose to be ambivalent on ZKK. I won't say I'm anti-ZKK but I'm not entirely convinced it will happen. We still have yet to see answers about Zoro's connection to wano, so there has to be a big zoro moment at the end of this arc. Something that will tie together all the little hints we've got about zoro's backstory into one thing.
This could definitely be ZKK and if so, imo that would be really hype. But I'm also open to the possibility that it could be something else. Ryuma did defend wano from outsiders and the marines are trying to conquer wano. Perhaps Zoro could have a brief 1v1 with a navy admiral at the end of the arc. Something that parallels his "nothing happened" moment with kuma at the end of thriller bark.
