@Jai I believe that when Jinbe said Blackbeard was hunting DF users its so he can have the "strongest" crew ever. So to my understanding BB kept his DF book & is using it to know which fruit's he needs for the strongest DF powers. Then when his crew kills whichever person has that power it will go to the regular fruit his crew has then one of his crew members will eat that fruit & get the power.

So I would bet that next time we see BB & crew they will all have their own DF powers & I also believe that BB might have 3 DF powers for his self(strongest logia, paremecia, & zoan) & that might explain part of the significance behind the 3 skulls on his flag.
