Stranger Things: Season 2 first look, via Entertainment Weekly

Stranger Things' Twitter account dropped a cryptic tweet that seems to have revealed when Season 2 will premiere.The pinned tweet includes just an image of a Houston "weather report" promising some major thunderstorms on Sunday. That tweet coincided with Entertainment Weekly announcing Netflix will run a Stranger Things TV spot during Super Bowl LI, also on Sunday.But if you take a closer look at the image, the numbers seem to reveal a possible premiere date of September 8, 2017. (The difference between Friday's temperatures is 9, the difference between Saturday's temperatures is 8 and the difference between the barometric pressure is 17.)It's not too much of a stretch to imagine the Super Bowl TV spot will confirm that date, considering the millions of dollars Netflix is spending to get that announcement in front of as many people as possible.If that doesn't get you excited enough, Entertainment Weekly also debuted the first photo from Season 2. Seems like there are ghosts that need bustin' this time around.
