According to a post by Creative Director James L. Sutter, this will not just be a one-off product. Paizo fully intends on supporting Starfinder with a monthly Adventure Path, where subscribers receive pre-written adventures on a steady basis, similar to what they do with Pathfinder. The Adventure Path will also include new rules and new monsters to tinker with. It’s likely Paizo will end up releasing supplementary rulebooks for Starfinder, though there’s no concrete evidence of it yet.
Starfinder will be launching August of 2017.
