The SSG must be a great powerup and I can´t imagine that is just be new cyborg weapons, it take off Mihawk and co from the allies, it must be very powerfull think if the Navy was sure to deal with the Shichibukai, let see if the SSG can hold up the hype in the end.
I like this panel which little confirmed my point about the raid going to fail:
The "biggest war" which Oda hype up all the last years, which Kaido hype in his first reveal, it isn´t the war in Onigashima, it will be the war on flower capital where also the Navy is there, the biggest war will cover whole wano, the people will learn soon the next lvl of terror where Wano totally change to a pirate country, this is similar to the birdcage/Alabasta thing, with the only fact that Kaido will
successfully after he and Big mom taking out the alliance.
Oda said that this war will even surpass marineford, because we will see the new weapon of the Navy and for all the first time finally a ancient weapon in action!!!
The war who starting soon is just a build up for a far bigger war in two weeks later(one piece timeline) where the biggest fractions fighting each other, arc 3 will end with the tragedy defeat of the alliance and the win of Kaido&Big mom alliance.
