I've never seen a manga/anime in which a mystery figure has been revealed a chapter or episode afterwards. A lot of people are claiming that this is a 'filler' chapter because there was no development on this man but if he was revealed today, it would be rather underwhelming. It's good of Kishi to build up suspension.
On another note: now that this man is hinted at not having good intentions with Sasuke, who do you think this man is?
