Who's coming back?
Since the core cast is signed for six years, the better question: "Who isn't?" Sadly, you won't see much, or any, of Barb and Bob (RIP). But be prepared to see the return of pretty much everyone -- i.e., Mike (Finn Wolfhard), Will (Noah Schnapp), Eleven (Millie Bobby Brown), Lucas (Caleb McLaughlin), Dustin (Gaten Matarazzo), Max (Sadie Sink), Joyce (Winona Ryder), Hopper (David Harbour), Karen (Cara Buono), Nancy (Natalia Dyer), Jonathan (Charlie Heaton), Steve (Joe Keery), and bad boy Billy (Dacre Montgomery) -- else.
Contrary to reports, the Duffer Bros. are staying
Near the end of February, a report from Moviefone suggested the Duffer Bros. would drop their showrunning duties after Season 3. Netflix promptly debunked the rumor via Twitter, writing, "Don't drop your Eggos. Rumors that the Duffer Bros are leaving Stranger Things after season 3 are false." The initial story claimed that the brothers were being courted for newer projects, and while there might be some truth to that, they'll likely stay involved with Stranger Things until it's finished. As Matt told EW last year: "There hasn’t been anything dangled in front of us that’s been exciting enough [to leave]. To abandon this show before it's done feels wrong to me."
