New Character in Overwatch a Healing Sniper?

Overwatch! Seems like there's always something new happening in Overwatch, which is great for people like me. People who just... love talking about Overwatch, at every given opportunity. Yep, this is great.

But hey--Overwatch has been out for a good while now, and people are starting to wonder when we'll get those free new maps and characters Blizzard promised us in exchange for adding a stupid loot box system in their fully-priced game. Well, while we don't know exactly who our first new addition to the Overwatch roster will be quite yet, the Overwatch twitter has recently released a new image that hints, at least, as to who this character might be--a long distance sniper-medic.

And look, they even threw in some lore, with two characters whose names confuse and scare me discussing the healing rifle. Who could it be? Who will they be aligned to? Where will they fall in the strange-fan operated Overwatch family unit structure? Creepy aunt? Step-brother? It's anyone's guess.

We'll have to find out later.
