Stardock and Ironclad have been looking at what's next for Sins of a Solar Empire. One of the big things on our list is to implement a new memory model for the game. The reason this matters is that right now, it's hard to add more ships or structures into the game because of the infamous 2GB memory limit on 32-bit systems.
So in the coming couple of months, we're going to be working on a new update to Sins of a Solar Empire: Trinity that implements this. After that, we can evaluate new opportunities in the Sins of a Solar Empire universe.
