I finally managed to blitz through
ninety-three chapters.
Kabuto's a failure for relying on overpowered abilities, and the numerous backlashes (suicides by some Edo Tensei'd people and workarounds by Madara, Itachi and Orochimaru) caused him his deserving defeat.
With that resolved, we still have the problem of the Kages critically wounded, and Madara and Obito preparing the seemingly unstoppable Moon's Eye Plan. (The Kages part is just an obvious Tsunade death flag to me.)
As for Obito's past and Rin being "penetrated" by Kakashi, I think that there's still a possibility that neither Tobi nor Madara is involved in this, and the Mist's sheer expertise in illusionary jutsu caused the teamkill. Heck, it could be some Mist-nin mook who contributed to Obito's descent to revenge!
One question though. If Obito can share visual information with Kakashi, why wasn't Kakashi able to harness that? It might have been useful in info gathering. (It's possible that there's a certain range for the "sight-sharing ability" to trigger.)
[You also now imagine Obito knowing the plot of the Icha-Icha series because he has been reading it using Kakashi's eyes.
