Zoro and Sanji are both in completely different locations, Killingham is where Sanji is, and Sommers should be near where Zoro is.
Unless somehow Zoro and Sanji, or Sommers and Killingham switch locations, it does seem like the fight will be Zoro vs Sommers and Sanji vs Killingham.
Crazy that Zoro for once might get the goofy opponent.
Now wait till Oda goes from portraying Sommers as a bum to suddenly hyping him up during his possible fight with Zoro.
