A new Sins of a Solar Empire - Trinity trailer depicts a starship battle in the upcoming bundle of Sins of a Solar Empire and the Entrenchment and Diplomacy micro-expansions for Ironclad's space-based RTS game. Word is: "The expansions are unique in that they do not just add content, they change the core gameplay. Sins of a Solar Empire – Trinity will be an entirely different Sins of a Solar Empire experience." This concept is explored in a new preview by Brad Wardell on the game's official website, and there's also an interview with Brad on Big Download. You can view the clip on the YouTube and the HD version is embedded below.
