Nope, the Juubi will probably come back out and go into his final form.
I agree dudePeople, madara doesnt need the kyuubi or hachibi, because the juubi is already replenishing the chakra that lacks, that's why it is evolving.
About obito, if he dies, I think thr juubi would just come out.
I think madara will run away ....... he's key is the tentails to kill naruto and get the nine tails <<<<<<<<<<<
