I think Luffy defeats Kaido in a 1 vs 1, but:
- Kaido is going to die.
- Zoro is the only person that Oda has suggested might kill Kaido:
Until the above two facts change, ZKK isn't dead.
Luffy defeating Kaido in a 1 vs 1 isn't incompatible with Kaido's death; Kaido can just stand up again. He's an Awakened(?) Mythical Zoan and mere Ancient Zoans have been defeated several times:
I started believing that Luffy will defeat Kaido in a 1 vs 1 after Chapter 1010, but that simply means that ZKK will happen after Luffy "defeats" Kaido.
If you want to claim that ZKK will not happen you must refute at least one of the two arguments I made.
