Honestly, I can see ZKK happening just because of this page.
Yasue's speech literally talks about things that are happening in panels. The only one didn't happen is statement above Zoro about Kaido's head.
The problem is that Oda didn't set up how Zoro can easily behead Kaido, when it took Luffy so many attacks to hurt Kaido with his defense. Not to mention for Zoro to get up in the first place.
