Next chapter we will probably see the whole broadcast reactions from all One Piece factions (World Government, Marines, Underworld, Revolutionary Army, Yonko, Shichibukai) and the true riot will start.
Many parties won't be happy with Vegapunk's death, as Vegapunk used to trade weapons to pirates in exchange for money for his investigations.
And not only that but the true about the World Government/Void Century. This will cause the nuke.
So... Here we are, a lot of people will now get out from the shadows and start to play serious.
He was always right.
And the winner is... Vegapunk, from the Revolutionary Army!
Vegapunk is/will be the trigger.
EDIT: This is the "battle royale" Oda said it's gonna happen soon, an all vs all war.
