According to the 2017 Stakeholders report, seemingly no plans beyond all the stuff in the TFT kickstarter. Yes Munchkin is the cash cow. And yes the current effort is labor of love re-releases. Since that means LOTS of Ogre stuff at DE/6E scale, I’m happy.
In any case I backed the TFT kickstarter as I no longer have any of my original Metagaming stuff.
