personally, i think that kakashi is dead right now, BUT, if i remember correctly j-man died, and then came back to life! but then died again lol, but j-man also didnt have any medic nins nearby when he came back to life, instead he got blown into the bottom of that lake, so my guess is that kakashi is dead, but he wills himself back to life and sakura saves him, or the white fang chakra within him is unleashed!! haha the last part would be epic but there is no evidence of that whatsoever
