After the jutsu has ended, the sacrificed one is dead.
Is it me, or is it strange that there aren't any new theories or at least resurfaced old theories about Tobi's identity ? After the confirmation that he isn't Madara, I expected some 'Tobi = Obito or at least uses his body' theories to come back at full force ;P. Especially since:
- Kakashi is at the stage of Naruto vs Tobi fight, where Naruto promised to rip off his mask,
- Obito's left side could just have been phasing through the rock, like Tobi currently can,
- just like with Orochimaru's 'take over for 3 years jutsu', there could have been a need to grant some wish (?) - a present (Sharingan) for Kakashi,
- the same type of Sharingan (?) jutsu like Kakashi's,
- more ?
If he were to indeed end as like that, damn, just how much of a master troll Kishi would be ;P.
