Barles, while I was reading your post I suddenly thought a terrible thought... that thought was "We haven't seen Sakura for a while...". If she somehow turns up and saves Kakashi I can see it as being both good and bad, the bad however outweighs the good for the reason Barles stated. However the only good thing I can see coming about if Sakura turns up and saves Kakashi it will show that Sakura will always be a useful to anyone in any fight they get in regardless of how powerful the opponent is. However it will also suck knowing that Sakura could save almost anybody from death regardless of how badly hurt they are.

On the off chance that Sakura does turn up and save him I'm guessing it will probably put Kakashi out of commission for another month or so again. I still think Kakashi is a goner however.
