From the looks of it,Sanji vs King isn't yet a given and some other person may really interfere next chapter like Marco for example.
King was able to block Sanji's Kick while being invisible,that actually speaks for his Coo and the guy is totally unfazed by either the slash he received by Kawamastu and Izo's gun.
Next chapter time for Zoro,law and Kid to start fighting seriously hopefully.
