Blizzard had confirmed that there would be a spectator mode for Overwatch in the near future. It seems they are working hard to ensure the spectator mode for the upcoming Overwatch League Season 1. It would be really exciting to see the new spectator mode, but obviously we are not allowed access to it yet.
Looks damn good.
