So some spoilers are out. They haven't been confirmed yet.
We get to see the remaining Kage. Each has a two other nin accompanying them
Tsuchikage is short old man who's complaining about his back pain. Accompanying him are two nin. A man and a woman that go by the names Akatsuchi and Kurotsuchi.
Mizukage is a woman with a similar appearance to Tsunade. Joining her are what is most likely a member of the seven swordsman and some other guy named Ao.
Also in this chapter, Team Samui asks Naruto to tell them everything he knows about Sasuke, but he refuses and tells them he won't rat out a friend. Instead, he gives them the line about not spreading hatred and tells them to take out their frustration out on him. They proceed to beat the crap out of him.
Last, but not least, we find out Danzo is contemplating killing/attacking Anko, and finding Kabuto in order to learn some of Orochimaru's ninjutsu in order to restore his arm and eye.
