He will low - mid diff next 1-2 Opponents until going serious again. There is a pattern. Every major PU Zoro always low-mid diff his opponents never going all out.
For Example when he got Asura in Enies lobby, he had an high diff fight with kaku. After that, he kind of mid diffed zombiefied ryuma. And he was fighting with two swords against zombie oars.
Same pattern with King. He awakened advanced CoC and learned KoH. He mid diffed lucci and sleep diffed kaku in their rematch. He even didn‘t use KoH in his clash with nusjuro.
My Predictions to Zoros next Opponents:
Shiryu - Low-Mid Diff Material
Nusjuro - mid - high diff material
Fujitora - high diff material
Mihawk (assumably last opponent) - extreme diff material where he gets a new PU (a kokuto)
