Oh sh*t is right! GM ! And we still have all those other Edo's running around.
Wow so now that Madara has a rinnegan, he can completely control the gedo mazo and summon it at will like Nagato did. I guess its safe to assume the gedo mazo is gonna release that dragon type thing from its mouth and remove everyones soul.
Finally, the REAL war begins!
GM might not be easily able to suck out the Kyuubi from Naruto, or KB might sacrifice himself. Either way it's just guessing until Kishimoto has the final word.
Of course now that Madara has the rinnegan things could be different and he may have the ability to make the GM suck the bijuu quickly but ya like you said at this point its guessing.
Killerbee is done for, sad to say. Also I think Madara may have killed the shinobi guarding the Rikudou's treasures. If he opens that large gourd/flask, kinkaku could be released.
It's gonna get real intense soon. Also, hard to make out by that pic, did Madara implant the second rinnegan also?
