So, this is a theory that I've thought up after rereading a few older chapters. It's a bit more speculative than I like, but that's half the fun. In chapt 625, during Hashirama's flashback sequence, Madara tells Hashirama a portion of what the Uchiha Tablet says.
"Looking for stability, one God was divided into Yin & Yang. The action of the two opposing forces created all things in Nature."
At first glance, this looks like it could be about the Sage and how he dealt with the Shinju. However, I think this refers to something entirely different. Primarily, because 'all things in nature' already existed well before the Sage ever split the Shinju's chakra from it's physical form. So it could be alluding to something else. Instead, I think this message is about a primordial being, of which the Shinju was originally a part.
Why? When the Ten-Tails was first revived, Kurama told Naruto that it was the 'Progenitor of All That Exists'. Yet later it was revealed that the Ten-Tails was an instinctual creature lacking thoughts or feelings, and that it's original form was the Shinju, which seemed to be entirely passive until Kaguya ate it's fruit. It's hard to see how such a being could be responsible for the creation of the world on it's own.
Furthermore, throughout the series, trees have been strongly linked with 'Yang'. For example; Hashirama, representing the 'Yang' aspect of the Sage's power, possessed the ability to manipulate trees. Naruto, who possessed the Yang Chakra of the Nine-Tails, induced strong reactions in trees when he accessed it's power. I don't think the fact that the Shinju is a tree is a coincidence.
So essentially, it's possible that the Shinju is the Yang aspect of the primordial being that was 'divided'. This means that there is a being that embodies the Yin aspect as well.
And this is where Madara comes in. Madara is absolutely confident in his ability to take control of the Shinju and ultimately the Infinite Tsukiyomi. Yet the question is how? He can't be planning to become it's Jinchuuriki. He no longer has a way to restore his body, and it seems to be beyond that point anyways. So what's his trump card? My guess is that it's the Shinju's Yin-based counterpart.
We know that it's possible for shinobi to summon spiritual beings, the Shiki Fuujin proves that. More importantly, from Minato we also know that it's possible for an Edo Tensei to be a Jinchuuriki, if the sealed being involved is Yin-based. So Madara could be planning to summon the Shinju's spiritual counterpart to become it's Jinchuuriki. As Yin represents the mind, this could allow him to take control despite Obito's status.
In all likelihood, I'm probably wrong, but most theories turn out that way regardless.
