You realize that the fight is far from over right?
Kaido is a Yonko and possesses a df so there is a very high probability that he will possess awakening. If his awakening is like normal zoan awakening then his strength and recovery will increase at minimum. Which means the fight with Kaido is far from over.
When have you ever seen the main villain leader fall before any of their top subordinates fall. It doesn't happen. Even Jack has returned yet people think that Kaido is done.
Depending on how strong his awakening is it might be nearly impossible to keep Kaido down. That's where Zoro we're coming to play. Remember, Oda did say in one of his q&a sessions that Kaido is not the type of character that would be defeated by being punched.
ZKK still very much alive.
