People underestimate the meaning of King and Queen for the end of the raid.
I don´t see them going down before Kaido getting his own flashback.
Both King and Queen will play a huge role and not getting defeated this fast, Kaido is the blue ogre when King is the red and Queen the green ogre. Each of them will have a meaning for this war, King flashback isn´t something who get finished easily likes from WsW...
And WsW in general or any other flying six can´t compare to King and Queen. Both carry the beast pirates for over 20 years as
@Chrono said in his thread. Both defeat the scabbards when they fought Kaido in the past.
I pretty sure the fight with King and Queen will go down for very long, until Kaido flashback ends, then I can see them going down, but not now. Kaido,King and Queen are around the same age, they are going down next to next...
