I find it funny that itachi despite having the [power to see everything in the universe.] and has proven to have extremely finnesse sensing skills(he figured Sasuke's not dead when the entire Akatsuki thought he was), so much that he sensed The Masked Guy out, couldn't figure out his real identity.

How come such a highly potent sensor never figured out his identity when he could sniff him out? Was that really 'obito'? Not to mention Obito has never shown the Jinchuuriki Genjutsu to control Kakashi/Guy/Killer bee/anyone else.
