Doubt tbh. Usopp never actually gained any powerups. Nothing here indicates WsW is defeated. Oda also isn't going to finish Jinbe's fight first, UNLESS his fight is actually with Jack. It's not his style.
Eichiro Soda is the worst fucking mangaka, I'm gonna drop this trash manga. Man drawing disgustings chapters, no fucking tension in the final battle, chapters focused on fucking tama and this lil trash taking 3 breaks per months since 2 years with 50 assistants doing all his fucking work.
Oda focusing on Jinbe vs Who's Who before Franky and Robins Fights? Very interesting... wonder if this means Robin and Franky will potentially Lose or something special is going to happen to them. Since Oda usually takes out the strongest opponents last.Found it weird that Sanjis fight was getting shown as early as it did compared to the other matchups.
I personally think it may indicate Jinbe vs WsW is not his final fight. Either he passes of the fight to Brook (breaks the floor below him to end up near Brook) so he can fight Jack, or he personally defeats WsW early to do the same thing.
Either this or it's just a chapter of fighting as his main fight and Oda decides to change focus before anything major happens anyway
