At this point you have to be trolling, no way you are this fucking delusional, there is no way you read the last chapter and thought that Zoro would fight Killingham or still think Usopp would fight him.
This is not like it was back in Wano, only some dumb Lanji tards actually thought that he would fight King, every other sane normal person knew he was going to fight Queen.
This is different though, Sanji vs Killingham was already being setup, with Sanji being the one to defeat him that first time, Killingham telling Sanji to remember his name, Killingham taunting Sanji, and finally Sanji going after him.
Even Zoro vs Super Super Sommers was kind of being setup too, with Super Super Sommers asking who Zoro was, and Zoro looking at Super Super Sommers's mechanical heart wondering if he could die if he destroyed it.
Did you even read this panel here, or did you purposely ignore it, Zoro notices Zaza at the village and he could have gone back, but he doesn't.
Meanwhile Sanji is the one that goes towards the village where Zaza and Killingham are.
They are not going to switch opponents, you are just coping because you were wrong about your Usopp vs Killingham matchup, and you don't want to see Zoro fight Super Super Sommers who lost multiple times.
