Honestly, the fact the Straw Hats are fighting alongside Jinbe against the enimies of this arc is a lot like how all the other Straw Hats join before because they all needed help from Luffy at one point before and Luffy would have to have fought against the main enemy of an arc to save them.

Zoro: needed saved from his execution and from ax-hand Morgan. Nami: needed saved from Arlongs tyranny and her people to be freed from his control and free her from being a slave. Ussop: needed saved from the Black Cat Pirates from destroying his island and stop Kuro and Jango from killing Kaya. Sanji: needed saved from Don Krieg from taking the Baratie and stop him from killing Zeff. Chopper: needed help from stopping Wapol from taking the Drum Kingdom back and killing him and the others on the island. Robin: would only finally need saved at Enies Lobby from the CP9 agents after seeing how the Straw Hats were willing to go to save her, finally gaining her will to live again. Franky: needed saved from Spandam from taking him to Imple Down and keeping the Franky Family alive. Brook: needed saved from his 50 years of lonelyness and getting his shadow back from Ryuma and Moria and defeating the zombies.

And now Jinbe: needs his island and the people and royal family saved from the NFP and stopping them from taking over and Jinbe did needed saved from being killed (though this was part of the plan).

Plus, when they were fighting in the arcs, at first they weren't considered as part of the crew till after the enimies were defeated and they all settled after the battle. So, Jinbe fits in this pattern of joining and in the end, I am positive he will join.
