It's a bit tricky to implement subtitles for the new cutscenes, because they are not separate video files like the original game's were (and the inclusion of subtitles might be one of the reasons why the original game has them in separate video files).
It can be done, but with JK/MotS' original "Print();" command you can't control for how long the text will stay on the screen (this was and remains a major issue in TODOA), so hopefully at some point OpenJKDF2 can implement a specific print command for subtitles that could control that.
I do have a classic FGR-style stopgap workaround (namely, adding in a new cog to each cutscene level which would time when the text would appear on the screen with the "sleep();" command) in mind for how to implement cutscenes in the current version, but got no estimate yet when I could get around to working on it.
