They may or may not get additional crew members before this, although I'm fairly certain Coby will be the last to join the crew. Since the poneglyphs inevitably conceal the truth about the World Government, I'm fairly certain that they'll be seen as a main antagonist of some capacity at the end (or second to end) and Coby will be put into a situation where he'll want to defect, and he'll be taking the six styles with him, probably. Just a guess. Could ironically have him acting as a cabin boy, too.
