When Hawkings predicted they would not survive a Month, a whole month of time in One Piece, we should known how big this arc can get by the final stages.
We still have 2 weeks in One Piece Time according to Hawkins and we are already at the cusp of war. With this speech of the New Onigashima from Kaido, I am now more assured that they will lose this first battle and it will be quick and harsh.
Oda did not start this New Onigashima plan for nothing, just like he didn't bring up Marco for him to not come to Wano.
Kaido will atleast enact some part of his plan, before failing. It will take place in this arc. Marines are coming. SSG ARE COMING. How Many will they unleash on Wano potentially, hundreds?
As many believe, I think the SSG are the improved version, the final realized version of Pacifista. Sleeker androids with all kinds of DF powers, maybe multiple DF powers in one SSG Android.
