The D6G recently interviewed Spartan Neil and discussed the background of the Firestorm Universe and SG's plans for this year. The interview itself is behind a pay wall, but here are the key points:
-There is a major push underway to upgrade all minor factions in the game to Patrol Fleet levels, to include releasing a box set for each one. So,more example, if a fleet only had on or two model types before, it will be fleshed out to 3-4 so that you can have a "pure" faction fleet for that race.
-There will be new (or, at least, newly playable) factions released as part of this effort, including the Saurians. Also mentioned were the Pathogen and the Overseers.
-Spartan will be releasing downloadable documents that will cover specifics on tech and organizations from the universe. Specifically mentioned was a document describing how fold space drives work. The goal of these documents is to help players flesh out the setting with technological limitations.
-There will be a range of materials coming out that will support campaigns in Firestorm. This will include a high-res map of the Galaxy, campaign notes, and possibly a set of rules.
Interesting stuff!
