In an interview with Entertainment Weekly, "Archive 81" showrunner Rebecca Sonnenshine confirmed that while Season 2 of the show hasn't been greenlit quite yet, the show is all good to go when Netflix hopefully chooses to renew. 

"I hope so, but I actually have no idea," Sonnenshine said when asked whether there are new episodes in the show's future. "But I hope so. It was always meant to keep going. We are always thinking about season 2." 

Sonnenshine was also gracious enough to reveal just how much of the story the makers of the show have planned out, and by the looks of it, they have a whole bunch of excitement just waiting for the green light. She confirmed that Dan's indeed in 1994, and stated that the people behind her family's fate will be revealed in Season 2, should there ever be one. 

"There are a lot of little Easter eggs or little things like that, that if you're like, 'I wonder if that's something that is part of the mythology and that will be explored further?'" she teased. "And, yes. Some things just didn't actually make it into the season. When you build a mythology series, you build out all this mythology, and then you're like, 'Oh, we don't have room for all that.'"

Fortunately, it appears that "Archive 81" is turning out to be a success story, so there's a decent chance that fans will see more of the show — and all those intricate plot points and mythology Sonnenshine teased — in the not-too-distant future.
