If you look closely at that image, the cursor is actually all the way over in the support section, which sparked much discussion over how a support sniper might play. That is Widowmaker’s pose though, but they were probably just using it as a placeholder, since it seems likely this new character will also be a female…

Sombra means shadow. Maybe there’s something in the shadows that won’t appear unless we shine a light on it?

Jeff’s response makes it seem like the community hasnt even scratched the surface of hints found in game.
