So its pretty obvious that the Obito-Madara team-up has gotten shakier over the last few chapters. I got to thinking how it will finally end when one decides he is through with the other.
I think Madara will realize that Obito will run their plan into the ground if he isn't stopped so Madara will put Obito into a genjutsu similiar to what Itachi did to Kabuto. He will then have Obito use the rinne tensei (like Itachi made Kabuto release the edo tensei) to restore Madara to "real" life and not an edo-tensei body. Thus killing Obito and allowing Madara to take full control of the ten tails without further interference. This will also solve the plot problem of how to kill an immortal madara as now he will be "killable" again.
So what do you guys think? Is this realistic, if even possible? This is my first prediction so don't be too harsh.
