A New Overwatch Character is Coming This Month
While Blizzard hasn't expressly announced the reveal of a new character of Overwatch, San Diego Comic-Con has basically done the job for them. A panel titled "Behind the Scenes of Overwatch's Newest Hero" will be taking place during the show.
The description of the panel reads: "Blizzard developers James Waugh (director of story & creative development), Michael Chu (senior designer, Overwatch), and Arnold Tsang (assistant art director, Overwatch) present a behind-the-scenes look into the creative process of developing the art, design, and story for Overwatch's newest hero."
The Internet is abuzz with the idea that the reveal will be Sombra, a possible Support sniper whom took part in the battle which allegedly killed off Reaper and Soldier 76 before they reemerged wearing slick masks.
