U wrote about jinbei's goal , that He dreams about a free World without slaves but this isnt a special dream of him. A lot of Charakters want a open World. The Amazons, the fishmen and a lot more.
Everyone in the strawhat Crew have a special dream/goal. Zorro wants to be the Best swordman, usopp wants a brave warrior etc.
I think that jinbei needs the same and i hope that Oda gives him a special goal. The best shipman or He wants to find a mystic object. ..

And i found a Interview in the last manga book , a fans asked oda about a colourspread, where u see all second strongest crewmembers.
And Oda answered that Not all characters on this picture are vice captain.

U See Zorro also on this picture And it could be that oda means Zorro wirh this Massage. Soo, this could mean that the straw hat Crew need a vice captain

Oda's Plan to finish One Piece in 5 years isnt possible. The wanokuni Arc needs actually 10 or 15 Chapters. So February or march should be the the end.
And after Wanokuni should be start a Lot of another arcs.

Luffy needs the Meeting with Dragon and Shanks
Elbaf
Meeting or something like this with Vegapunk
Battle against the World goverment
And to find the one piece with the last Fight to be the Pirate King, verses Blackbeard

What is with Masked Deuce? He was the first Member of Aces Spade Pirate crew. We heard from him only story's in the novel. He didn't want to say his real name and he wore a mask.
He only wanted to write stories about his journey l. Maybe the first member of Ace could be the last member of the straw hats. And they have a man to write a book about the journal of the future pirate King and his crew.

Carrot complete her goal after this Arc. She travelled and saw Whole Cake Island and Wanokuni. And she becomes her revenge when she wins against perospero.
And the last point is, she is a member of the mink tribe. This tribe have a traditional connection with the Kouzuki clan. Wano needs help after the war. She will be a part of the newstart.

Yamato could be the newest member. She is strong, fights with a special weapon, ate a devil fruit. It could be that her goal is the same like Oden. She want to travel But she rode the diary and she knows that Oden had another dream. He wanted to oped Wano.
So, her main dream could be to help Momo to open Wano and to protect him.

I think that Koby will be the last member. He has the same points to join the crew like the other members. And he could built a new navy after the war.

The last panel of the last chapter said thousand words. This picture showed us the whole crew. This crew isn't complete but in this moment. And it showed us that carrotvor Yamato aren't a part of the crew.
My favorite is the unknown visitor, who met crocus and LA boum. He made the same long way like our crew. That's one big point. Carrot and Yamato only saw Wano, Zou and Whole Cake.

Yamato isn't safe for me to become a Nakama.

She fought against her dad several times. It could be a training. Maybe it is a plan between Kaido and Yamato to catch Luffy.
Why should say Kaido that he wants Yamato to become the Shogun?

It's sound weird.

Guys and girls, what is with Yamato?

The Japanese translation is, he, who brings the peace or the warship.
He is a hero in the Japanese story to use the kusanagi sword.

Why should this guy be a bad boy? He don't like the festival, so this mean, he doesn't like Kaido. And Kaido doesn't like him.
He must be a adoptive children or like this.

And his name work with the another shp members.

Luffy - l
Zorro - z
Nami - n
Usopp u
Sanji - s
Chopper - c
Robin - r
Jinbei - j
Brook - b
Franky - f
Yamato - y

I would imagine that the crew still needs a tracker / scout. Someone has the idea of ​​a treasure hunt and traces and hints can follow or read.

The actually stand say me, we have four names.

1, Blackbeard - he is the antagonist
2. Imu - he is the Leader of the government
3. Sakazuki - he killed Ace
4. Rocks - when he is still alive than maybe he

Carrot would be a nakama for the crew but not a member. She is too young for luffys crew, the crew have a "pet" with Chopper and she has no position.
I see 2 solutions.

1. Koby will join the crew after the Reverie cause I will find out the secret of the government and that Imu will kill someone of the nefetari family
Or Garp fall in this battle verses the Revos Or he joins the fight verses the emperor's and fall there.

2. We become a completely new character.
