Can someone explain to me, logically, why this mysterious person would be Shisui?

Because the motivation seems to be "He loved Itachi, Sasuke killed Itachi, therefore he hates Sasuke", completely ignoring the part where Itachi manipulated Sasuke into killing him and was in fact going blind and dying of disease - things he would know if he knew the whole truth about Itachi and the Uchiha downfall.

If he *doesn't* know the truth, then why would he hate Sasuke for killing him? His last words to Itachi were that he should protect the Uchiha name. How is slaughtering the clan protecting the Uchiha name? Even if you look at it in a morbid way (the dead can't sin anymore, after all) Itachi became a disgrace to the clan's name, and Sasuke killed him partly to wash out the "psychotic mass murderer" stain. And Sasuke has in fact restored the Uchiha name, as much as it can be restored.

As far as I can tell this theory requires Shisui to be a completely different guy than he was shown to be. Now everyone cites Obito, but there was enough ambiguity and in fact we did get a more or less coherent progression of his descent into villainy. What such motivations does Shisui have, though? It can't be "Itachi died" because clearly he understood the value of sacrifice and so why would he bear a grudge? It can't be a broken promise because the only person that he extracted a promise from was Itachi, so why would he be mad at Sasuke? Why in the first place would he want to kill Itachi's legacy?

Of course, logic will probably not matter in the end because the whole miniseries is shaping up to not make much sense (Sarada's parenting drama, yo). But personally I'm of the opinion that whoever is under the cloak is merely using Shin, and doesn't particularly care about Itachi either way - their vendetta is probably just with Sasuke himself or maybe even Naruto (but they can't get to him in comfy Konoha, so they have to draw him out somehow). It wouldn't be the first time in this manga that a mysterious person lied about their motivations so they could manipulate their subordinates. The Juubi doll in particular makes me think it could be someone with ties to Madara/Obito, not Itachi.

Of course, we could also have the regular ol' villainception where the guy under the cloak is actually a resurrected Shisui who's under the control of yet another guy in the shadows...
