I think Zoro’s either gonna find Yamato or run into Who’s who. Maybe both.
But that’s not gonna be his main fight this arc, His main fight is going to be against King. I think King is either gonna find Zoro with Yamato or he’s gonna run into Zoro after Zoro’s beaten Who’s who.
Now Zoro having a play in Kaido’s defeat Could still happen but I think it’s less likely if Zoro has an all-out fight with Kaido. Just look at Luffy after his fight with Katakuri, Zoro will likely be on that level after his fight with King.
