Itachi did say that there was one more capable of awakening the Mangekyou Sharingan, it's possible he was talking about Kakashi, but it's also possible that somewhere he stashed a female alive. Somehow I feel like Mangekyou should have been a bloodline only trait and not a feature of the eye alone like the perception and mind scrambling.

Anyway, I think Sasuke is probably more concerned with revenge at the moment and won't worry about revival until after he's finished with that.
