I respectfully disagree. Obito has a lot of exposition and I doubt his story will just be ended like that in a single chapter, being Madara's lapdog power ***** and going out like this. He's living like Rin is watching, now. He's gonna phase out of Kamuiland, give Madara the finger, then go and save Killer Bee. Other reasons for his survival include:
1. The restoration of the Uchiha clan. It'll need more than just Sasuke because he's most likely impotent.
2. Kabuto and Obito have both become full fludged faces with Kabuto speaking of Obito pensively. They might do a Nagato 2.0 and revive everyone.
3. It'd be cool as hell to see Kakashi, Obito, Gai, Genma, and Ibiki just chill after the war. The 5 of them get some sake, play some cards, go to a gentlemen's club and stare at some titties, and bury the proverbial hatchet.
4. Obito is a tank. He's survived being crushed by boulders, point blank Rasengans from Naruto and Minato, Kyuubi Susano'o combo attack, Juubi extraction, and 10 million paper bomb. To have Madara just tear his eye out and be done would be... just wrong.
But, then again, his death is somewhat called for. I'll play this one like I did/am with Gai, I guess.
