Captain Jack Finds a Home
Though the wait is lengthy, the important elements remain: Russell T. Davies as show-runner and executive producer along with Julie Gardner, and of course the two remaining core characters Captain Jack Harkness (John Barrowman) and Eve Myles (Gewn Cooper). There does seem to be at least one interesting setting note according the press release :
"Torchwood has to date been located primarily in Cardiff, Wales. The new series will allow Davies and his writing team to tell a more explosive and global story..."
"Torchwood will burst back onto the screen with a shocking and moving story with global stakes and locations that will make it feel bigger and bolder than ever."
I'm not so concerned with where Captain Jack's home base is as I am with having the same core group running the show. Since they pretty much had to bring on most of a new team anyway after Children of Earth, Jack and Gwen are really the only essential characters. (Other key cast will be announced soon.) So roam if you want to, Jack Harkness, roam around the world.
