Overwatch : Something Is Being Declassified On April 11th

The official Overwatch Twitter is teasing something that's about to happen in the hero shooter on April 11th, something called "King's Row Uprising." What could it be? Blizzard loves to play game so we won't have any information beyond pure speculation until the day of.

Considering the tease is of classified data "entered into record 7 years ago," with a "mandatory robot registration" banner blinking in the background I'm going to say it's not a new map or new hero. Maybe a new game mode? Maybe a PvE game mode?

Then again maybe it's just a cinematic, or the start of another ARG, or more cosemtics? You never know. We'll just have to wait and see.
