Well, Sakura still has her seal, so she in the end may save Obito by somehow transferring it to him. She must still have it for a reason. Also, I don't want to think the panels the last couple of chapters where she worried about him were for nothing. Also, it's obvious Obito is trying to commit suicide, and that's not a good thing. The chapter ends with him being penetrated, and his body starting to crack. It would be more believable if he died right there, instead of waiting for next chapter. Many characters went through similar situations (Naruto, Sasuke, Gai) of looking like they'll die, but ended up being saved in someway. Obito hasn't been any different throughout his Heel-face turn.
Since we saw what looks like Rin's apparition, does this mean we'll see others? Maybe Kushina ?
