This obsession Sasuke fans have of him getting the other half of Karama's chakra makes me laugh.
I'll be honest, if Naruto doesn't get the other half there isn't any chance that SASUKE will.
Not even considering the fact there is absolutely NO Way Minato would give it to Sasuke, There is no way Sasuke would WANT Kurama's chakra. He looks down on Kurama, or at-least that's the way I view it.
All-together, I really don't think ANYONE will be getting the other half. I could be wrong though.
