I am going to make this very, VERY clear to everyone: Orochimaru AND NOW KABUTO CANNOT DIE BY CONVENTIONAL METHODS. Orochimaru's fight against the four-tails is evidence of the white snakes resilience. Even after Orochimaru was chopped up into several pieces when he faced Sasuke, he still lived and subdued the Uchiha fledgling. There is a reason why the third Hokage tried to seal him with the reaper death seal. there is a reason why Sasuke had to suppress Orochimaru's spirit/chakra. There is a reason why Itachi had to use the sword of tetsuka to seal him away. these traits are now passed onto Kabuto. Sasuke has no known sealing techniques, and even amaterasu can be countered by Oro's style substitution jutsu. Sasuke cannot hope to defeat Kabuto and i suspect that Kabuto has methods to avoid the power of the sharingan when his "tranference ritual" takes place.
