well look the characters that will appear in New World

are Buggy (and i'm pretty sure he's a Shichibukai) Also Rob Lucci (he told spandman in the mini cover he will return). Crocodile and Daz Bones (they went to new world too and i can't wait to see their new bounties). Enel (he went to an island somewhere in the grand line but it's not stated where,so i bet it's in the new world). Oimo and Kashi (Dorry stated that Elbaf is on the other half of the grand line). Finally they will meet the other supernovas and the Yonko Blackeard(7 of the supernovas including Luffy and Zoro have already been seen)

And i shouldn't forget Aokiji.
