It's something avid fans have been pining for ever since finishing the first season, which proved a massive hit for Netflix.
I don't know why it was speculated for ages. Obviously it made sense to renew it.
Season Two will make its debut in 2017 and will consist of nine episodes, that's one more episode than Season One. Bosh!
On their path to an answer, they discover a murky and mysterious world of government experiments, the supernatural and a creepy little girl.
Netflix has given the new episodes the following titles:
The Boy Who Came Back to Life
The Pumpkin Patch
The Secret Cabin
The Lost Brother
The first season stars Winona Ryder, David Harbour, Finn Wolfhard, Millie Brown, Gaten Matarazzo, Caleb McLaughlin, Noah Schnapp, Natalia Dyer, Cara Buono, Charlie Heaton, and Matthew Modine.
On a scale of one to 'bring me the IV, I feel faint!', how excited are you?
