@choperman:
Thoughts are that Basil Hawkings is the last shichibukai and the drake is now one of kaidou's top elites
I don't think it would be possible for a supernova to survive two years on the grandline when right from the start he pissed a yonkou off, my guess is he wanted his attention so he could join him, no way a newbie (albeit a supernova) could stay alive two years from constant attacks by a yonkou and his allies, he's probs a top member now
and Hawkings is constantly said to be in the rankings with Kid, Law, Drake and Luffy my guess is their the elites but the other guys are monsters as well
now what I'm wondering is are many of them still just regular captains or have they all got new groups, like working for a yonkou being a shichibukai or something else
Pretty much agree with all of this.
As for your last question, I think Law hit the Jackpot by becoming a Shichi. He can do whatever he wants, his crew is pardoned and the members could theoretically go back to their families, but I have the impression they would follow Law wherever he goes - especially the named characters.
If Drake joined Kaido, which is very likely, I think it will be like Ace joining Whitebeard. The crew will be integrated into Kaido's fleet, possibly under the command of Drake (among many others who were already in Kaido's crew, but surpassed by Drake).
Kidd has his own crew like before, nothing changed as far as we know.
Hawkins probably still has his crew or "cult" at his side, he uses them as living shields / fodder for his devil fruit.
Bonney probably lost all her men after being caught. I wouldn't be surprised if she escaped again, but escaping + freeing her crew? Unlikely. Half of them is probably dead anway due to Blackbeards first assault.
Leaves the "lower" Supernova captains: Apoo, Bedge, Urouge.
I would like to see at least 2 of them completely shattered - like Moriah.
One of them by Big Mum. The Straw Hats need a proper demonstration of her power, and seeing Capone Bedge's corpse on a random island would help. Imagine his dead body hanging on a string, filled with candy - to serve the monsters of her crew as a pinata.
Just think of something gross, I'm sure Oda can do better than I.
