It's really difficult to predict what will happen next, but I'll give it a go.
Because he let Shuu live I am inclined to believe that Kaneki still cares for his friends and is with the CCG only because it is required to rescue Hinami. It's kind of a stretch, but maybe Kaneki will collaborate with Aogiri / Eto to get her out.
It's obvious that we'll see the repercussions of Kanou obtaining the knowledge behind the Q's surgery, and we'll be seeing an increased amount of artificial half-ghouls. Urie's focus will lie on getting Shirazu back, so we might see some interaction between him and Aogiri / Kanou.
Other than that, I'm really not quite sure. Will Shuu go into hiding, and if so, with :re? What will the :re gang be doing now that they know Kaneki has his memories back?
And how does Kaneki intend to die in style? Arima alone might not be able to be enough at this point, unless he just holds back.
