Overwatch – Blizzard Teasing Either a New Hero or Map…Or Both?

The Overwatch Twitter has a new teaser up that simply says, “Calm before the storm” that seems to be teasing either a new map or hero or perhaps both. The image shows a wall of graffiti that shows a large image of Lucio on one side, another saying 0 bots and yet another for “equal rights for Omnics”.
