Overwatch Hero Announcement May be Coming
Rumors are being bandied about that we are about to get the announcement of a new Overwatch hero, to celebrate the one year anniversary.
A thread on Reddit points out a discovery that the official YouTube channels of the game from multiple different regions have updated their playlists. People believe that Blizzard has uploaded new videos but set them as private/unlisted.
The playlists which were updated are Cinematic short, maps, events and developer update.
This practice has been carried out before when it uploaded videos of Orisa in March. It is completely plausible that this has absolutely nothing to do with an impending character reveal, but all routes point to something being announced soon.
