If tobi is obito, then kakashi isn't going to die. At least, not before the madara comes and reveals his evil plot to kakashi. Not to mention, Kurenai is also going to want to tell him how she's really pissed that back then, he really did leave her to die after taking her eye. And when Gai's finally done laughing and gloating at Kakashi's death, he just might save Kakashi for some insidious purpose. This damned Neiji is really a mystery.
