I mean, it seems sort of hard to explain after the ending of Avatar, but I've been seeing rumors flying around the internet about it. Personally, I'd be perfectly fine with him returning. I love Stephen Lang and I loved his portrayal as Quaritch. He seems to have a knack for playing villains.
For all the other Stephen Lang fans out there, I've also heard he's great in The Monkey's Paw, where it looks like coincidentally he also plays the villain: http://monkeyspawthemovie.com/
How would you guys feel about Quaritch returning?
Either way, looking forward to December 2016!
