Tbh, I can still see it happening. The Ryuuma parallel is uncanny. Not to mention the likely Shimotsuki connection they share (literally Ryuuma, Ushimaru, and Zoro all have a ridiculous uncanny resemblance with their faces).
Now, I've never used that as a measure to prove Zoro HAD to fight Kaido the entire rest of the arc. That was my whole point. Its possible to believe ZKK can happen if we dont apply blind fanboy logic to everything we think may happen with this upcoming Yonko fight.
So far, these matchups have pretty much told me that only the Strawhats seem to be fighting the executives. We now have each F5 distracted by only Strawhats, and now have Sanji and potentially Yamato (assuming she's Strawhat material) free to take on at least 2 of the 3 YCs.
I will NOT discount Zoro vs King because of it. Oda has a tendency to make matchups as clean as possible, and if he's intending to have literally every strawhat get defining moments and fights (add Chopper to Nami/Usopp's fight or just Page 1), then I can see the same logic here. Give any of these fights to people like Drake or Marco and it sort of defeats the purpose that new gen pirates are supposed to surpass these Yonko. With Drake being a Marine and Marco being an old Gen pirate, I just dont think its in their place, but who am I know or judge until things happen.
This to me just "seems" to be the moment where every strawhat will be used to surpass a Kaido executive. If Brook went to fight WsW, I would have been more receptive to a certain someone else fighting King, but no anymore lol. Hes definitely staying with Robin at this point.
