I think I saw this coming when the idea of Jinbei joining was put out, infact... I believe back at Arlong Park forums someone predicted a fishman Helmsman back as far as 2004. Wish I could congratulate them.

It was made pretty clear back in Arlong Park when Luffy was saving Nami from her enslavement, that Fishmen are good at sailing ships but they can't find a good navigator, therefore the whole thing was spelt out then. So we've known for a decade for Luffy to have the best helmsman it was going to be a Fishman, in my opinion.

The only surprise is that it ended up being Jinbei. As a former Shichibukai, it means Luffy's crew in terms of strength and reputation as lept up. Think about it, at the beginning he was recruiting nobodies and Zoro was his best known member... The recruitment ladder has gone up since the East Blue. From Robin to Jinbei, the scale has slowly climbed, with Chopper being the only oddball recruitment since the Grand line started, as he had little fame.

I expect someone from a Yonkou will join at some point, making Luffy take a bigger step up. From the Shichibukai, you can only go up by getting someone from a Yonkou to join.
