It doesn't add up to be Shisui, I mean like I said before if he was alive all this time then he would know what went down between Sasuke and Itachi, so there's no reason whatsoever to get revenge on Sasuke.

The hooded man might be someone new who was also working behind the scenes, but didn't make himself known as Obito and Madara had done or could be someone already introduced as apart of the Uchiha, but their backstory wasn't really gone into. The hooded man says he wants go after Sasuke because he killed Itachi or at least that's what he has the "boy with the Sharingan" believing, but I'm starting to think that maybe Itachi didn't know this person because wouldn't he have told Sasuke after they defeated Kabuto. Because then that was like Itachi's tell all, he said he should've trusted Sasuke could do it. So it would've made sense for him to tell Sasuke about another Uchiha then still keep a secret.
