Sanji vs Queen already started few chapters ago and i don't think Queen has anything to show now since Jack got threw away like nothing. So 1 or maybe 1.5 chapter (i means 26 or 27 pages of fights panels only which is really big), so with talk + revealing = 2 chapters is safe or maybe 3.
Zoro vs King, 2 sure or maybe 3 chapters (but 3 is enormous since it's equal to 51 pages of fight panels

) so 3 or 4 chapters for talking. I mean Zoro AND King need to show lots of things, the latter didn't have that much screentime so maybe Oda will give him more.
Even Kaido vs Luffy is just one or two pages of fight per chapter and the rest is just talking.
