manda 2 has legs! damn!!! the previous chapter was overflowing with action and information, it is now my most favorite recent chapter.

madara will use the chakra of the captured bijuus by virtue of his having the body/dna of hashirama so that he can make the 10,000 zetsu clones copy his powers and soon we will have an army of madara -- doing the phasing and the invincible jutsus with the mangekyo sharin'negan. not to mention he has sasuke with his new eternal MS. that explains his hubris when he went to reveal his moon-eye plan to the kages and declare the 4th ninja world war. looks like madara will really win this war.
and then there's kabuto.
we know what he is capable of. and he's proven that he's scarier than orochimaru.
is kabuto really for or against madara?
and will kabuto return to madara with both/either naruto and/or bee?
if that would happen then that would really cripple the alliance and make the odds even greater for madara to win.
that is why i don't think kabuto'll be successful in bringing either of the remaining jinchuuriki. besides these are the two best loved characters/jinchuurikis we have. i don't think they're going down with just a kabuto. no matter how powerful he is -- being the reincarnation of orochimaru and all -- with the edo tenseis of fallen akatsukis and a mystery character in the 6th coffin (which tells us kabuto is not going down either, so we shall see who this 6th character fighting against madara).
i don't think there is much to see with kabuto fighting the 2 remaining jinchuurikis, or with him even capturing at least yamato. UNLESS kishi brought kabuto there as an equalizer.
here's the more exciting scenario. kabuto gets captured by the alliance and squeals the info. or he 'sells' them the info for a fair trade -- either to spare him his life or for a chance to study yamato. or kabuto would offer himself as a spy.
i have this feeling that kabuto isn't really loyal to madara or to anyone but himself (that's why he's a 'serpent' to begin with. like his master orochimaru who 'betrayed' akatsuki.)
kabuto went for madara so that he could supplant him, since madara seems to be the 'new' orochimaru for him to 'learn from' and 'copy'. i mean, anyone could sense how madara's 'inventions' excited him. he discovered/found madara and his hideout. he saw how madara has been successful in cultivating hashirama's dna. and he saw how madara got the mangekyou sharin'negan as well as the statue that contains the captured bijuus. and the 100,ooo zetsu soldier clones.
AND ADD TO ALL THESE the fact that kabuto has lead konoha to discover where ALL THESE are located -- madara's HQ.
kabuto carries the secret that would reveal the weakness of madara, and he also possesses the 'second life' of itachi -- who is yet to reveal the secret of madara and the real (not anymore an illusory) story about the uchiha massacre to sasuke, which tells us that they'll be a sasuke vs itachi match part 2.
sasuke shall fight kabuto and kabuto will summon itachi -- and we'll have the exciting match of seeing for the first time a battle between an EMS vs an MS. and in the aftermath, we'll see if sasuke gets to turn around.
in all of these i am saying kabuto holds a very important role as the great equalizer. He as the third-party in the duel between the alliance and madara, and one who will either build or erode the great powers of the two parties.
