I didn't think of Obito referring to the Susanoo, it makes sense if Kakashi keeps at least one Sharingan, considering there's the little narration at the end with the "This eye will copy the future" stuff. We see Obito gave Kakashi the necessary chakra to create two Sharingan, and we know Uchiha have better chakra reserves than the average, so it's logical that all Kakashi needs to keep up a Susanoo is more chakra, the Sharingan however he doesn't need the same amount as chakra to keep, and the Sharingan are material while the Susanoo is literally made of chakra. I can definitelly see it be the Susanoo not being used normally.
