Just my thoughts
Kaido is called wisdom king in Wano, befittingly his attacks has been referencing the names of the five wisdom kings of Buddhism.
"Conqueror of Three Worlds" Ragnaraku(Trailokyavijaya)
"Vajra" arrow
"Kundali" Dragon Swarm
"Yamantaka" Thunder Bagua
We're still one attack short of finishing the collection, missing the Acala(immovable wisdom king), the center of the five wisdom kings. Naturally I'd imagine Oda would give Kaido's strongest attack this name.
In conclusion, I think there'll be at least one more chapter of their fight.
