Well Madara want's to become the jinchuriki,but it will be extremely hard for him since Hashirama wont allow it to happen not to mention Naruto and Minato with their speed.
Still as crazy as Obito is he would not allow himself get controlled like that it would be embarrassing and downgrading for him.
I think we will see the final transformation since the 10 tails will soon go crazy.:snick:
