This should have happened a long damn time ago.
Agreed. I'm sure someone will point out all the little storyline reasons why this couldn't have happened sooner. But seriously, for overall plot and character development reasons, this totally should have happened a long time ago. (Like 7 years ago after the timeskip, when Naruto was still interested in using the Kyuubi's power. Before Kishimoto made Yamato talk him out of it, that is.)
