They did tease Lucci back in Dressrosa already, with even more showtime as his CP-0 role in the non-canon Gold movie. Kaku was more new however.I'm a simple man. I see Charloss getting punched in the face, I like the chapter.
Also, Shanks might be talking about Luffy... or e might be talking about Blackbeard. Considering if you will we have Big Mom, Kaido, and Shanks in the chapter, as much as everyone loves chatting about Luffy, my bet would be on Blackbeard being the subject of the next chapter's conversation.
EDIT: Oh yes, and Rob Lucci is back. Was wondering where he went. Guess he got a promotion!
Unless she actually is the queen of that kingdom aka his wife? hard to say because as far as i know we don't know her true ageWhy does Im-sama gotta look so damn silly for the de facto ruler of the world? Also, poor Kuma. Wonder what connection Bonney has to him to get all teary-eyed; daughter, niece, sister or something otherwise related to that kingdom?
