Re: Kakashi's death?
I got it. Orochimaru will make one of Kakashi's shadow clones evil and attack him. He'll also use an Itachi-zombie to keep Naruto and Sakura from saving Kakashi. While fighting evil-Kakashi, Kakashi will have to avoid Kisame (who's sword can somehow fly now), and Madara's MS. All the while, Zetsu is saying, "I'll eat you when you're dead."
Oh, it's going to be awesome!
