Margaret Weis Productions has expanded its Serenity license, and will release three Serenity RPG products next year. Early in 2008, it will release a collection of short adventures; late spring brings Six-shooters and Spaceships, a ship and technology sourcebook; and the Big Damn Heroes Handbook is slated for next summer, probably as a GenCon release.
The Serenity RPG core book has gone through multiple reprintings (see 'Serenity RPG Back to Press'). And the release of a collector's edition DVD later this month (see 'Serenity Collector's Edition DVD') will give the browncoats somthing to watch until the next RPG products are released.
