Blizzard Teases New Omnic Event?

Blizzard teases new event – Is it about Omnics?

Today is the day on which Blizzard uploaded a video on their official Twitter page with the following Tweet: Initiating archive declassification… Mission files unlock: April 11.

As you can see in the video, it has something to do with the map King’s Row, which received a small update in the latest PTR patch. Does this have something to do with it? Near the end of the video, it shows, what looks like to be Tracer with perhaps a new skin?

We know that there won’t be an Easter event. Perhaps it’s the first event not based on a specific time of the  year? Judging by the video, we may get more information on April 11. What do you think the event will be?  Let us know in the comments below!
