The editor must be updated for the new version. Which we'll do for the Steam version (Steamworks integration). When that is out, anyone will be able to create expansions for the game, including Catacomber. And we can then select those which are good enough and talk with the creators to bring them to mobile (iOS/Android).
I'm still working on Cloud saves for Android (it turned out to be very difficult, not in small part because of the buggy C++ Play Games library from Google, which had to be dropped and everything rewritten using the Java library...), when it's done, I can add Islands of Ice and Fire to the Android version as DLC. Then I can start on the editor (which will be a lot of work).
