And we still have Jinbe to come at any point, the fishspitter prisoner, the missing Tobi Roppo… also Oniwabanshu, minks and the other pirate crews can break into multiple characters if they don't move always as a group. So far Oda is handling everything fine, but it will be a challenge when the plot lines start developing and intertwining.
