Theory for Sanji vs King still happening.
Sanji fighting Queen is only to free Chopper so he can heal Zoro.
King is going to try kill Tama/Nami/Usopp and the gifters who turned by using his "Wildfire" attack, Sanji will use RS to fly to 2nd floor and jump in front to take "Wildfire".
Queen uses Hyper Beam to kill Tama but Zoro comes out from medical area and uses 720 pounds cannon to clash/block.
No one can get close to King while he's using "Wildfire", Sanji emerges and kicks him into building.
Sanji vs King
Zoro vs Queen (Zoro can't get hit or he'll suffer more)
Let me believe...
