Re: new bountys!
List of what I think the next bounties is going to be:
Luffy: 450 million seems reasonable enough. Eustass Kid, who has 470 million, has roamed free in The New World in two years now, and I can't imagine Luffy exceeding his bounty in just a week like that. (Yeah, it's probably just been a week or less in the One Piece world since the timeskip.)
Zoro: Around 200 million is what I guess (Probably 190 million). You said 330 million, which is waaaay to much for a vice-captain right now in the beginning of the new world. Basil Hawking, who is one of the 11 supernovas including a captain, has 320 million Beri in bounty, and I highly doubt Zoro is going to exceed that.
Sanji: 150 million bounty. Killer, the vice-captain of the Kid Pirates and a supernova, has 200 million in bounty. He has roamed free with Kid in two years, and Sanji exceeding him on the first bounty in the new world is just unimaginable.
Usopp: 65 million bounty seems good enough for someone in the weak-trio He isn't weak at all now, but I think that's good enough for him right now.
Nami: Since I believe that Nami won't exceed Usopp, then I think she'll have about 50 million as a bounty.
Chopper: I seriously think Oda is going to troll Chopper, and give him an only 100 Beri as a bounty :p
Robin: 100 million beri as you said seems good, but there's still a high possibility it's going to be higher than Sanji's bounty, because of all the "a threat to the government" thingy.
Franky: 125 million Beri is a good bounty for him. Higher than Nico Robins, and lower than Sanji's. You said he would get 200 million Beri, the same as Killer, which seems so unlikely.
Brooke: 90 million Beri. It seems good enough for our cool skeleton here
