1)Kabuto was once a young boy in the Hidden Leaf Village, and he was adopted, but sense no one really new him, he was just trained as a spy. Along with being a spy, they gave him medical ninjustu so that he could fool the enemy into thinking he was a innocent person if he ever had to. However, being a spy made he pretend to be many things. While doing this he started forgetting who he really was, and the Leaf Village did too. That's when they just kicked him out. With this, Kabuto wanted revenge, and here in this chapter, he ask for Sasuke to join him, but Itachi calls Kabuto a bigger lair than himself.
2) Itachi uses something called Izanami at the end of the chapter, which is basically the upgrade from Izanagi (the thingy to decide reality and destiny that Danzo used). Izanagi changes the destiny, and then Izanami decides it. I guess it will be fully shown and described in the next chapter.
3) Itachi told Sasuke that he will tell him all of the truth after they defeat Kabuto, but I think that's just another lie by Itachi. I believe that the Izanagi is suicidal, and that Itachi will die with Kabuto. After all, Sasuke is turning good way too fast, and Naruto should be the one who saves Sasuke from the darkness, not Itachi.
My prediction: This is a though I just had, and this might just be so stupid, but hear me out on this one. Naruto said he wanted to save Sasuke from the darkness and bring him back to the Leaf Village. Well... what if Kabuto summons more people with Edo Tensei, and they all kill Itachi and Sasuke. Then Sasuke is forced from the dead to be evil, and Naruto has to save him, but to do this, Naruto has to kill him and Kabuto, and everything else in his way. After defeating Sasuke, Sasuke finally says that he can finally see the light again, and Naruto buries him at the Leaf Village. This to me somewhat makes sense. I mean, Sasuke has killed soldiers, Danzo, and maybe a few others. These crimes cannot go unpunished. However, with death, he won't need to be forgiven. All people will need to see is Sasuke telling Naruto his final words.
Oh.. and maybe while Sasuke is saying his final words, Hinata makes out with him before he dies... THE END!
