Big mom has tons of fight chapters in this arc and the last two just add more fight scene, I like Oda not forget her and make a long good fight, the way how Oda write the Big mom fight and also the two remain calamity give me hope for a good long battles for Sanji and Zoro too.
As I said with Drake and Apoo making a alliance, I can see them attacking Queen, both literally join sides because of Queen.
If Queen didnΒ΄t attack Drake during the raid, he probably wouldnΒ΄t change the sides, if he didnΒ΄t throw Apoo into front of the dogs and even try to killing him, he wouldnΒ΄t betray Kaido for now. Everything is linked to Queen and Sanji is right now in big problems since he want not to end as his brothers, Oda open up a possibly where Drake and Apoo can gang on Queen until Sanji comeback.
I think Drake and Apoo get 1-1,5chapter against Queen, showing there strongest moves, however Queen defeated both of them who even hype Queen more then enough. Sanji comeback for a second round to battle of Queen.
I can see a similar scenario for King vs Zoro, with Zoro learniing more about the past and Ryuma, King also dominating the fight.
Sanji and Zoro most like get a big powerup, this arc is the right time for Sanji and Zoro to became monsters on their own.
I think in compare King and Queen getting CoC and awakening.
That is at least how I view the rest of the fights.
