@Marcotty:
Huh, weird. I hadn't pegged the fight as being over at all. I got more "Shut up and let's get serious" vibes from Jinbe's big hit than any sort of expectations in it being over. It wouldn't surprise me at all if Who's Who stays up, shakes it off, and makes a bet with Jinbe, gambling "My information about your captain's fruit for any information you have on the sun god." on whichever one of them can win their fight.
If it would be just the punch in the face I would agree that it's not necessarily over, but looking at the big picture:
1. They fought for some chapters with minor updates (Jinbe beating up his crew, WW going through Full Zoan & Human mode).
2. WW already anounced he would fight seriously the moment he entered Hybrid mode.
3. Jinbe didn't just punch his face, he broke his fingers and his wrists. WW is heavily handicapped if he would get back up.
4. Oda dedicated roughly 1 full chapter to their fight, if we count half of last chapter and the previous updates on their clash. That's the regular battle length for non-Luffy Straw Hats, and to be honest pure luxury in this war. Personally I would LOVE more, but that's just super greedy.
5. The Nika stuff demands attention, but it wouldn't surprise me if Oda just wanted to make the most of the pages. I mean we're at a point where everything has to be viewed with the end of the series in mind, he can't afford to be super wasteful anymore and "only" deliver a cool Jinbe fight. He needs to throw some breadcrumbs while he's at it.
I just wonder who or what will occupy Jinbe now, that could be an argument. Because he's basically unscathed (for Jinbe standards) and no one else is free to take him. Maybe he could join Law & Killer vs Big Mom, or deal with the remaining Numbers?
