Firefly Online is the continuation of the TV series, folks. It's all we're gonna get, and it is what it is. So, I'll take it. But there's more to the upcoming FFO than I realized. This behind-the-scenes video—featuring voice acting coach Andrea Romano—reveals that she's gotten (a chunk of) the crew back together.
I see Mal. I see Wash. Shepherd Book is in there, not to mention Dr. Tam and River, too. And if you download the Firefly Online Cortex app, you'll have access to the longer video interview. I don't know why Jewel Staite (Kaylee) isn't there, but Sean Maher (Simon) gets emotional during a reading and says he brought a picture of her with him to the studio. And while Morena Baccarin didn't make the vid, there's an official FFO photo (on Steam) of her doing some recording.
Firefly Online is shooting for a Spring 2015 launch on Windows, OS X, iOS, and Android.
