I don't think Coby ate a devil fruit. His power, in that respect he'll be similar to his mentor Garp,comes just from strength and haki. After 2 years training I'd probably put at him a Commander /lieutenant commander with Helmeppo one rank below him. The Shichibukai, the only one I could possibly see becoming one is Basil Hawkings (if it isn't a new character), because the world government wouldn't give the position to the civilian slaughtering Eustass Kid (he wouldn't want to become a Warlord anyway), neither to Law, because of his involvement in the War, nor to Drake, seeing that he is an ex rear-admiral. And judging from what we've seen so far from the Supernovas, hawkins might be the only available one that is strong enough. Buggy will probably be one too. Fleet Admiral will hopefully be Aokiji (although we might be in for a surprise there). Smoker, also notorious for refusing promotions will probably be a Vice or Rear-Admiral.
