I think that for a large amount of chapters, Obito will be able to control the Juubi and use it against the alliance and battle against Naruto. The fact that they are now both Jinchuuriki's adds to the tension between Naruto and Obito. Naruto controls and gained the trust of the Bijuus through love and acknowledgement whilst Obito intends to control them through Power, almost like the beliefs of the elder son and younger son which supports that Obito will be able to control the Juubi till the end.
But there is some evidence to say he might not be able to control it. I saw this theory stated on another thread (can't remember who posted it) that showed the Panel of A's cousin saying that to be a Jinchuuriki, you need something to fill the heart. Obito stated himself that he has no heart as has abandoned all feelings. This suggests that Obito will control the Juubi for some time, but the hatred will eventually overcome him.
