So, Whole Cake Island was supposed to be Sanji's arc, and Sanji fans were wildly disappointed.
Wano was supposed to be Zoro's arc, and Zoro fans were wildly disappointed.
Elbaph, the island most tied to Big Mom, is now where Sanji gets his actual hype power ups.
When we return to Wano for Pluton/Act 4, we will see Zoro get his arc, finally, and visit Ryuma's Grave.
I was hoping Elbaph was a Sanji power-up arc because of his ties to Big Mom, and Gyaban's presence more or less confirmed it.
I guess Zoro needs to meet Rayleigh before he takes his next step.
