Looking at Oda’s Tobbi Roppo Route, Zoro vs King only has 1 chap left.
Intro Chaps
Jinbe vs WsW - 998
Franky vs Sasaki - 998
Robin vs BM - 1005
First chaps
Jinbe vs WsW - 1017
Franky vs Sasaki - 1004
Robin vs BM - 1020
Second chaps
Jinbe vs WsW - 1018
Franky vs Sasaki - 1019
Robin vs BM - 1021
So for Zoro now its been…
Intro Chap - 1023
First Chap - 1027
Second Chap - Unknown
Could be next chap or a completely different chapter. Id prefer the Jinbe v WsW and Robin v BM route, with both chaps following each other. Franky vs Sasaki coming randomly with one chap seemed lame.
