The pieces are starting to fit indeed, and regarding to what someone said about the Juubi in the earlier chapter, yes, that sight of the full moon with the juubi was indefinitely a foreshadowing of things to come. This is not the end of the Juubi, in fact, I would like to know more of it's real body in the moon and such, and this may be a stretch, but what if the true problem isn't madara or the juubi? What if the sages evil son or something is somehow involved with the moons eye and such?
Madara isn't a problem in the context that he isn't evil, his actions are, but he wants peace, and has no qualms in killing to go for it, and as I said in another thread, he is searching for something, seeking answers, so what if the true problem is a character none of us have seen yet? Just a interesting thought there.
