Why is everyone talking about Orochimaru like he's dead? That was just the part of him that was preserved in Sasuke's cursed seal. Also remember that the only reason why Sasuke was able to beat Orochimaru was because he was weakened and in need of a new body (plus he made a sneak attack). People always seem to forget that Kabuto took what was left of Orochimaru and it's slowly taking him over. Kabuto said something about not knowing what the end result of the transformation would be, but seemed to imply that it would be something very powerful. Orochimaru seems like he's been itching for a chance to take on Akatsuki, how amazing would it be if "Kabutorochi" of all people put the fight in the Leaf Village's favor?
A guy that fights with eight swords, that should be interesting, though it's already been done in One Piece.
