The key is that it's an akatsuki cloak. But the only true akatsuki that's left is Orochimaru. The rest died. Even for Orochimaru it makes no sense since he despised Akatsuki.

So who is it? probably a new character. Well, i guess Hidan is left but the guy seemed un-hidan like.

Lastly, it always was a stretch to me that every last living Uchiha was in the village when Itachi ended them. Really, not a single one on a mission or travel?
