The Susanoo without eyes thing is really strange to me. It does seem as though the Mangekyo is only required to awaken Susanoo, not use it. We've now seen Madara, Indra, Sasuke, and possibly Itachi all activate and maintain Susanoo without activated Mangekyo. But if that's really the case, why did Sasuke always activate the Mangekyo to use Susanoo in the past, even though doing so pushed him to the brink of blindness? It doesn't really add up.
