User blog comment:The Bonehead Skipper/The new member is former shichibukai .../@comment-222.154.68.233-20101014060042

I agree with the person the third entry below mine. It seems plausible that if any new character would to join, it would most likely be jinbei, he has the same character, integrity (for leaving the shichibukai etc...) as the rest of the SH. Still not sure even if another member will join, but if they do get a new one, my bet is on Jinbei as he is already pretty strong, but not too strong to dwarf Luffy and others now that they have had 2 years hard training.
