A new video teaser has also been put out.
By the time "Stranger Things 3" begins streaming, it will have been nearly two years since fans were last treated to new episodes, with the most recent run streaming from October 2017.
Fans have until July 4 to figure out what exactly that means.More news: Putin still 'open to dialogue' with U.S. , says relations important for security

Here's the poster, its tagline being "One summer can change everything". This time around, these new episodes are going to be set squarely in the middle of summer, with the 4th of July holiday serving as a centerpiece to the action. And oh, what a odd, unusual summer it will be.
In the foreground Mike and Eleven hold hands - but stand very far apart - as Eleven stares pensively back at the camera. But Ele senses something is not right. It's fit with crackling audio and VHS tape lines, and includes footage from Dick Clark's New Year's Rockin' Eve in the moments leading up to the "big apple" dropping to usher in 1985.
There's also the reinforcement of The Starcourt Mall theme in titles including The Mall Rats and The Battle Of Starcourt. But it is all interrupted by an eerie transmission. Mysterious interferences interrupt the broadcast, sending static onto the screen along with unusual messages like "when blue and yellow meet in the west". There is a word.
We already know the names of the eight episodes in the forthcoming third series, which were revealed in early December.
