Touchstone comes in on the Sci-Fi setting level, and if the Kickstarter reaches that level you'll get the basic systems of the Touchstone Trilogy as part of the settings guides (ie. a breakdown of the powers, the places, and the types of missions available). [And I'll get to write that part of the setting guide! ;) ]
I'm not otherwise involved with the Core Rules or Popcorn Press, but for those who loved the world of Touchstone and want to play around in it (or just like tabletop gaming and can never have too many rulebooks!), check it out!
