Well...this looks promising.
Madara is on the battlefield now.
Basically no one stands even a remote chance to win now.
Not to mention Kakashi's overuse of Kamui is getting up with him, in just a few more I'd say he collapses.
Wich means Tobi could likely fight the other 3 on his own and win, let alone with Madara.
And even if they'd win by some miracle, they'd have to be fast, the Juubi is getting revived as they sit there being baffled about tobi's hideous face.
When the juubi is out, its practically over.
So...sleep tight in infinite tsukiyomi everyone, after all, its for the best.
