The Overwatch Uprising event is ready to roll again, this year starting on April 10th. The announcement was made on the Overwatch Twitter in the usual cryptic fashion. The small video seems to be hacked possibly indicating that Sombra will be playing a part in the event.
There are a number of theories about this year's event including a Blackwatch theme as the logo appears in the Twitter post. You may also remember that Moira's origin video showed her in a Blackwatch uniform too so perhaps she'll be receiving a new skin.
So far, we don't have any confirmed information about Uprising beyond the date, but it's likely Blizzard will release more next week. Keep your eyes peeled!
