Forum:Possibly another Shichibukai?

Throughout reading the msot recent arc, I have been getting a vibe that we might see someone that we haven't seen in a while. A lot of the events in this arc have lead me to believe that Donquixote Doflamingo will make an appearance. First of all, the various kidnappings and disappearances mentioned by Tashigi sound right up his alley based on the events with the Human Auctioning House. Also with the inclusion of Law, we might find out the greater significance of the "smilie" considering that both Doflamingo and Law both have the nontraditional smilie instead of a jolly roger. Doflamingo may be the "Joker", the name seems fitting for his overall insane character, and constant laughter. Since he is really the only Shichibukia that we havent really seen, I hope that we get to see more of him soon.

Any thoughts/comments/opinions/predictions?

Thanks!
