I too like to mine the source books for useful extras. I play (primarily), in a custom post-apocalyptic setting that has a lot of advanced Sci-Fi elements and have cribbed bits from Terrinoth and SotB. I was dubious about Key Forge until I got it and it also proved useful. Thus I am a little more optimistic (Than I would have been) about something like TI, again, primarily for adding new ideas.
So, while I doubt I'll be running a TI game, and I am admittedly fairly ignorant of it's setting, I can certainly imagine it'll be a good resource to add to the ever expanding pile. I just don't know enough about the theme to anticipate a wish list. More gear is always a plus!
