Here's a video of Lynette Rice talking a bit about what to expect from the article. Warning! There are spoilery images of season 3 and a bit of discussion about season 3/Voyager plot lines. Do not watch the video if you want to remain totally unspoiled.
There's also a short write-up accompanying the video, with a minor potential spoiler, that mentions there'll be an interview with Maril on "Outlander Live!" on EW Radio (Sirius XM 105), October 3rd at 2 PM ET if you're so inclined to listen. They'll be taking calls and giving away an Outlander Season 2 Collector's Edition DVD set. Also, Diana Gabaldon will be at EW PopFest talking about Outlander on October 30th.
