HA ! here's a prediction for yall
it is said by kishi in a previous interview that 8 tails will invade konoha. i was at first thinkin it was to capture sasuke who mightve been held prisoner, but i NOW think he might be recruited by akatski. before u attack me , just read on.
1) it makes sense! the sword makes him evil, he joins akatski,
2) raikage becomes too connected to the situation and is removed from head of the kages and they put kakashi in charge (year in the spotlight ring a bell?)
3) kisame (who i always thought was a somewhat good guy any way) is now good since he parted with the sword.
4) Afterwards after 8 tails is stopped then captured (and after Raikage begs) Naruto insists that Konoha forgives killerbee, therefore forcing the Raikage to forgive sasuke, and that way sasuke can come bck to the village with no fuss.
I also (tho this is most unlikely) want to see sasuke come back alive to konoha and be there when naruto becomes hokage. Have him like the danzo, working in the dark of konoha but not as evil/deceitful. that would be a beast ending in my opinion.
