Now that we've seen the full Stabilized Susano form of Madara, i've realized that Kishi is essentially setting up the upcoming Sasuke Vs. Naruto battle not to model the Madara vs Hashirama fight, but rather the original battle between The So6p himself vs. the 10 tails Juubi.
Stabilizing the chakra (biggest gray area from chapter 589) could = giving it real form. both in the sense of Susano's Final Form and the tailed beasts transcending being just massive chakra sources and forming their own bodies/ you could take it as far as souls/beings.
I'm assuming one of the main tools the So6p used to battle and win against the 10tails was the Full stabilized form of Susano. Obviously not saying that this was his only weapon but probably the only way he was able to overpower the 10tails.
