Do we know anything about Madara's plans? Many of us seem to agree that Obito screwed Madara's plan (Nagato is a traitor and dead, two bijuus are still at large). Yet what is Madara's plan?
We learned during his fight with the five Kages that he is a shinobi who considers himself unbeatable, now that Hashirama is dead. And he is right. I seriously don't think he has any interest in a Moon-plan. I am getting the impression Obito's reason for his plan is that he wants to establish an illusionary world in which nobody has to suffer. Maybe he even wants to resurrect Rin within the Tsukyomi. That would make love - in a sick way - his guiding principle.
Madara on the other hand isn't too much into love, but power. So my guess is that his plan is quite simple: Becoming the Jinchuriki of the Juubi in order to be the most powerful being in history, maybe even stronger than the So6P.
It's really a shame what happened to Kabuto. Having so many villains - Madara, Obito, Kabuto, Sasuke, Oro -, each with his own agenda, is going to be hilarious.
