How are the remaining Shichibukai gonna go down?

[AznDevil]

So anyone have some prediction of how the remaining Shichibukai are going down and who's gonna do it.

The current known members remaining are:
Dracule "Hawk Eye" Mihawk-Zoro is gonna take him down to achieve his dream
Jimbei
Donquixote Doflamingo
Bartholomew Kuma
Gecko Moria-From the looks of it It's gonna be Luffy again or maybe a Luffy and Oz Duo will take him down.
Also Blackbeard is aspiring to join.-I don't think Ace has taken him out yet, but I think he most likely will in the future either that or Luffy will be the one to.
I also kinda think Dragon is gonna take down one of the Shichibukai therefore showing his strength.
I also think Sanji deserves to take down one of the Shichibukai as he is one of the Straw hat's major fighting member. Based on absolutely no fact at all just a gut feeling I think it'll be Donquixote Doflamingo.
