Buggy blunders his way to further glory.
At some point Marco will take Weevil under his wing. Maybe Sphinx as a brief interlude at some point for the Strawhats where they can meet him, give Luffy a chance to see Ace's grave before he becomes PK?
I'd like to think Kuma's memory gets restored, cause he seems like an alround decent guy that really doesn't deserve what's happening to him. Fascinated to find out what Bonney has to do with him.
Mihawk will be fine, all this does is push him into the New World so Luffy, Zoro and Ussop can meet Shanks, Mihawk and Yassop (for the last time dun dun dun).
Hancock's the one to actually be worried about, since she's the one Oda's said something will happen to. Probably SSG's big victory- Buggy's too much of a joke character, Mihawk and Weevil's role in the story wasn't came yet. Whereas Hancock's kind of served her purpose.
Doflamingo's too entertaining to waste giving cryptic hints in prison. He'll get out and continue his love/hate relationship with Croc sailing the seas thinking they're bigger deals than they are.
And poor ol Moria keeps having everyone he loves killed off. Best thing he can do is get Absalom's body, stick a shadow in it, run back to Thriller Bark and hope to be overlooked in the wars to come.
