Madara's secret reveal?
As we all know Madara is using a still unknown techinque which grant him the power to "vaporize" and teleport any part of his body, or his hole body. In the last manga I have come across evidence that leads me to think that Madara isn't using any jutsu to avoid all attack and "Vaporize", he is stuck in that state.
On this page we can see that Madara is threatening Sasuke of fighting him if he attempt to continue toward the village.
Then when sasuke pass right through him, Madara immediately change tone by becoming more friendly and saying that it's no use to go there.
The moment Sasuke attack we can see that Madara is surprise by is boldness and realize that manipulating him with fear won't work.
But why always scheme and manipulation? If Madara is half the men he is suppose to be, he could have easily stop sasuke. I personally think that he simply can't, Madara is stuck being a chakra body like the tailed beast, but cannot physically interfere with others. For all we know of the EMS, the image we have of Tobi and his body could very well be a constant Illusion (half illusion, half real chakra).
I would even go further and say that all there is physically left of madara is his eyes. The ultimate jutsu, no aging, can't be harm. There is certainly a purpose behind all those zoom made on Madara Sharingan. Kishis so far as always given hint on all his plots, I think that he is revealing that Madara's eyes are not only the key to his secret, but the very incarnation of him, the only thing left of him..
