Coby might be as high as lieutenant or captain, but I wouldn't put him higher. Even at captain he's jumping up 7 ranks, which I suppose is reasonable in two years, but I wouldn't say anything above commodore. As for the new Admiral, I want to say one of the vice admirals would probably get it, I'm not sure who though considering how little we know of them. I could see Smoker possibly taking the place of that vice admiral though, or at least he'll be a rear admiral. As for Shichibukai, Buggy is a very good possibility. I also remember reading an interesting theory that the marines might force Jewelry Bonney to join, but that is mere speculation and an interesting idea. I'd also put a good chance that one or two of the other Supernovas might fill the Shichibukai void, but I couldn't say who. If I had to guess I'd say either Hawkins or Urouge. Hawkins because he has one of the highest bounties and would make a good addition to the group, Urouge because he seems fairly weak and would be foolish to decline the offer. However there's a good chance that it might just be somebody completely new as well, but considering Oda claims he has everything he needs to head towards the end, I'd say whoever it may be would be somebody already introduced, so they can just be elaborated on rather than completely introduced.
