Fans of the space strategy game Sins of a Solar Empire might remember that around this time last year developer Ironclad Games and publisher Stardock announced plans for three micro-expansions for the game to be available via digital download for $9.99 each. The first such micro-expansion, Entrenchment, was released last spring and the second, Diplomacy, is due out in spring 2010. But what about the third micro-expansion?

Today at PAX 2009, Stardock CEO Brad Wardell announced that plans for the third micro-expansion for the game have changed. Why? According to Wardell, Ironclad and Stardock have so many things they want add and improve to the game that putting all of them into a third $9.99 downloadable micro-expansion would simply not work. So what does that mean? Will there be a larger commerical expansion to the original game? Perhaps even a full-fledged sequel? Wardell admitted to nothing today but did say that fans of the original game should know that the future of the series is looking good.
