Not happening. The Seraphim have to stay in the hands of the WG, so whatever the outcome is has to favour the WG’s victory in that regard.
The Strawhats will escape, but they can’t take everyone with them, crowded as things already are. At the very least I don’t see more than 1 Vegapunk making it out with them.
Beyond that, Caribou is still on the loose somewhere, so it may be something related to Ancient Weapons.
