Pretty unexpected chapter. I think no one expected it coming apart from spoilers.
So the Shichibukais system is revoked... Seemed to be a smart move by the government considering it was visible they hadn't a compromise with the eradication of the pirates, with the Marineford war being an example, a war they did squat. I liked seeing Mihawk excited with the idea and we have seen Doflamingo again.
Sabo's death won't be a thing, likely... I think Oda has put it there more for reactionary effects, plus the emphasis put at Marineford at how there would be someone taking on Ace's will -- that one obviously being Sabo -- would be meaningless if he died.
Coby going to Amazon Lily also catches attention... Dunno how strong he has become, but I think that if he got into a confrontation with Hancock he'd be just turned into stone lol. But I dunno, maybe he has the determination of that Admiral who injured himself to prevent such.
