Kurama will recover the other half of his chakra.
This sort of dawned on me.
Unless Orochimaru can control which souls get released, then I believe that Kurama will get the other half of his chakra.
Since Minato was released, could it also be possible that Kurama will recover the rest of his chakra?
(If the pic does not show up, then please refer to page 10, 11, or 12. Forgot which haha.)
Although there are only 4 souls (soul-part, in Orochimaru's case), chakra would most likely not be in that certain form.
