Apparently there is a movement to create a new season of Firefly.
From there main page:
We are looking to push the envelope of episodic television by offering Season Two of Firefly in a groundbreaking new format. Each episode (or the entire season) would be made available for purchase in Standard or Hi-Definition.
It's possible that subscribers may choose one of three playback options; monthly DVD deliveries, TV On-Demand using your cable or satellite provider, or computer viewing via Streaming Download.
It's also possible that a box set of DVD's would be available at the end of the season.
I'm game. Just as long as Wash and Book are back. Unrealistic, I know.
