Since Oda ব্যক্ত One Piece has only just reached it's climax, we know there's a long way still to go. During that time I think we can expect at least 2 আরো crew members, as Luffy ব্যক্ত he wanted 10 of them. Jinbe is almost guaranteed to be the পরবর্তি nakama.
Yeah, I think we can expect two আরো crew members in the New World. Obviously we already know that Jinbe will be joining the crew, though not for a while. So, that leaves the crew open for two আরো members to make up the ten... we know Luffy won't change his mind about having ten people in his crew, since he's stubborn.
What I do think, is that the Straw Hats will make আরো allies in the New World.
