Official invites have not gone out yet, but Blizzard has set the official date of the Closed Beta. Noone knows who invites will go out to... but word is (from reliable sources) that content creators such as Youtubers, Twitch.tv streamers, Podcasters, etc... will be receiving the first round of invites. That makes sense, as Blizzard wants people playing the beta that will continue to build hype for the upcoming release.
That being said, I would assume invites will go out to a decent size pool of regular beta testers as well. They have to have enough population to have active servers at all times throughout the beta. Hopefully they will invite testers based on seniority with the beta sign ups. So those of us that signed up a year ago when the game was first announced, will have a better chance. But we shall see.
In the mean time, there is a ton of information available on
https://www.reddit.com/r/Overwatch
Youtube and Twitch will be breaming with info after the 27th as well.
BELL, can we get a "Other Games: Overwatch" section please? Maybe we can scratch some of the games we are no longer active in as a guild.
