Nice theory but I have to disagree with the intended target. In the panel where Obito lands near Gamakichi, MINATO yells at him to stop, getting his attention. Minato is standing in the middle/front, sasuke is on the left, naruto is on the right. It appears to me that he is going after his senpai, Minato.
Whats kurama thinking?
We havnt seen him doin anythng from last few chapies...
Rikudou did imprison him, it seems Juubi can't let go of past grudges =D
