Vessel for Susano’o? During the final battle between Naruto and Sasuke, Kurama says


  [Sasuke] might just become the next vessel for Susano'o.


Throughout the series, Masashi has never mentioned a "vessel" for Susano'o.

Was this just a translation error; what did he mean by this?
That's clearly a translation error. from what I read, Kurama says that he's merging the disseminated chakra into one.And since there is no Gedo Statue, he's using the Susano'o as the receiving vessel.
