The short answer is  that there will be no further updates to this demo. It currently includes the entire common route as well as the transition chapters, which is over 50,000 words of game content. The only other content in this game is the character routes. There's nothing else I can feasibly add to the demo and still call it a "demo."

As for new content "anytime soon" - I'm not sure how to answer this.

I'm working on developing this game daily. The writing for the base game is complete at 716,000 words of content, and I am currently working on setting up and coding the flowcharts before embarking on completing the CGs which are currently at about 30% complete. Currently, three routes are available for beta testers and I'm also working on correcting typos to those based on feedback. A fourth route will be going out to beta testers within the next week.

This game is in active development, is worked on daily, and there are updates posted to patreon, tumblr, and kickstarter on a regular or semi-regular basis. It is a massive game and is also a solo developer project so it's going to take some time for it to be complete.  I do not have an exact release date as on-going lockdowns that have required me to share my workspace with a distracting family member (bless him), computer issues, and family tragedy have all thrown me off schedule.

The game is currently just under 90% complete for the base game (not including the three stretch-goal LIs added during the Kickstarter).

If you're concerned about the state of development for Gilded Shadows, or else would like updates on progress, I strongly recommend that you follow the developer blog on tumblr where I update every 2-3 weeks with the progress I've made and what I will be working on in upcoming weeks.

Or else you can subscribe to the lowest patreon tier for weekly updates with screen shots.

Thank you. =)
