Thanks to tonytonychopper.xxxblog.jp we have the scans of that special book.
Some information, thanks to Greg in The One Piece Podcast Facebook.
It also appears to be confirmed in the booklet with the latest JUMP issue that Mihawk, Doflamingo, Kuma & Hancock are still listed as Shichibukai leaving two unknown spaces. Kuma? Still? Really??? Even though he was out of commision protecting Sunny so long?
More original info from the special booklet with the newest issue of JUMP (not officially released yet).
