We put this on our Discord recently. Never any promises/guarantees with game dev as a general rule.
"We're continuing to work hard on the Prince of Suburbia "Knock Me Up Again!" DLC. We're working as quickly as we can to develop this DLC but don't have an exact timeframe/estimate for its release yet. The hope is we'll be close to completing the art and writing for it sometime near the end of this year or early 2026.
We will likely have a mini-release sometime in the near future that we'll send out to Patrons and Subscribers. This mini-release will be for your enjoyment but also an opportunity to provide feedback to help us shape the rest of the remaining DLC."
The cost is TBD and TBA depending upon how much content and quality go into it which we won't know fully until we complete it.
