What happens after Pein and the Akatsuki are disassembled?
True, we have Sasuke and his group. Madara included. We have a rubbish Konoha. And a ton of ninja still waiting to show us what they got: Shino, Sai, Rock Lee, Neji, Tenten (is that a joke?), Kiba, and tons of others who have had almost no attention in Shippuden.
And then we still have Kabuto out there. Though if he really does get captured by whats her face and that other guy that quickly I will be eternally disappointed. The fact they tracked him down is already disappointing.
