Maybe Naruto, though not as powerful Madara, may be able to use this special power, and probably it's why the tailed beast was told to give Naruto their names. Maybe Naruto doesn't have to power up, or regroup. Maybe, he has what he needs already.
I honestly want to see Sasuke meet Madara. I wanna see how they'd talk to each other, and how Sasuke feels about Madara, and especially who's the better fighter (most likely Madara).
I predict another turning point in this fight and a major turning point in the character of Obito. Since Juubi is back, Obito can now cast his infinite tsukuyomi (How? I don't know..) but will Madara allow it? I doubt he's a type of man that seeks peace, he's more a person drown in his obsession with unlimited power so yea he might screw Obito's plan up and we'll see some change along with the backbone story of why Kakashi killed Rin.
I can see madara you're a fool obito, i was the one that set up rin's dead and i never planned to cast suck a stupid genjutsu and my true goal it'$ being a hokage as my true love hashirama and control the world mumumuhaaaa..
From what I understand, the Infinite Tsukuyomi was Madara's plan to begin with. Obito only agreed to the plan because he was told that he could bring Rin back from the dead.
I don't think Tobi can use Tsukuyomi at all. Chances are, Tobi planned to revive Madara and have him cast Infinite Tsukuyomi. If Tobi could use Tsukuyomi, he'd have done so long ago, on Minato, Naruto, and etc.
I don't think Madara said he'd bring back Rin from the dead, just that Rin would be there in the dream world.
I doubt that the infinite tsutuyomi is madara's real plan, madara like fight and have power over the world and yes in some way, madara will have power over everybody's dream but i doubt madara true goal is that perfect world that he being talking about.. i don't know, there is something fishy about his plan..
He has stated many times he wante dpeace and all that, so who knows? I could see Madara wanting to use Infinite Tsukuyomi to end all wars. Plus, as he is now he basically has no equal that could entertain him.
Now that jyuubi has been revived I guess at this point Madara's attention would divert from naruto and others to jyuubi..he probably would ask obito to cover him up while Madara attempts on being the host of the jyuubi..so I guess it wont be as bad as many has put forth..while Madara is temporarily out of the equation, kakashi and Naruto has ample time to either convert or finish off obito..or another situation that could develop is obito turning against Madara on becoming the jyuubi jinchuuriki himself rather than allow Madara to be one..how could Obito be convinced that Madara would revive rin once Madara becomes the jyuubi jinchuuriki??
