Overwatch has 20 Million Player Accounts, Halloween Event And Has Sombra Leaked ?

Overwatch is now 20 million players strong according to Blizzard. To celebrate this milestone, Overwatch is also getting a makeover for Halloween. Until November 1, all loot boxes have been replaced with glowing jack o'lanterns that contain more than 100 new costumes, highlight intros, profile icons, sprays, victory poses, and emotes. You can see them in action in the video below. Apart of this Halloween event, Blizzard has released the first-ever PvE brawl, called Junkenstein's Revenge. This wave-based event allows up to 4 players to team up to take down a mad scientist and his minions. In other Overwatch news, A recent leak, found by a Russian Overwatch group, has begun circulating online through Reddit  and suggests the character Sombra will be coming soon. The text in the image also references her origin as part of the "Los Muertos" gang, which appeared in the short Blizzard released about Soldier 76. If this is real, I feel like we’ll see Sombra at BlizzCon and she’ll become available a week later. Thoughts ?
