IT'S THEORY TIME GAIZ!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I believe that once Itachi disappears, Sasuke will free Kabuto from Izanami and violently order him to take over his body. Kabuto does so but the Immortality Jutsu backfires on him because Sasuke casts a Genjutsu powerful enough to wipe out Kabuto's consciousness to the point where all that remains of Kabuto is his DNA inside Sasuke's new body. Sasuke not only gains the powers of Kabuto, but the powers of Orochimaru, Jirobo, Kidomaru, Sakon/Ukon, Tayuya, Kimimaro, Suigetsu, Karin and Jugo as well. Sasuke will look like his old self, but have Oro's pale white skin and the purple markings around his eyes plus the yellowish eyes with slit pupils.
I also believe that Kabuto made some special preparations for Madara. Those being that somehow, once the bodies disintegrate and the souls of the dead are released, they will all be sacrificed to revive Madara. The souls will all head strait to one spot in the sky just above Madara's current location. The orb of collected souls will then blow up to shoot a beam of light that hits Madara directly. Those souls will then erase all traits of whoever was sacrificed for Edo Tensei Madara and then voila, Madara is alive and well. This of course means bad news for the Kages but hey, it beats having Madara get transported back to the afterlife because that would be one major half-assed cop-out after what we've been shown that he could do.
Whelp, that's my two cents to this chapter discussion for the day.
AND THEN HE BECOME SUPER SAYAJIN NV 4 AND, THEN NARUTO MAKES A GENKI DAMA WITH THE POWER OF THE WORLD AND THROWS IT ON SASUKE, BEFORE HE LAUNCHS AN KAMEHAMEHA THAT WILL DESTROY THE PLANET IF NARUTO TRIES TO AVOID IT.
