Like, at this point it's clear that the owners of the IP do not want ANYONE else touching it, but also can't put the work required into managing a release every 5 years or so. OH, did we mention that the metaplot for all of Sentinel Comics is tied up in the RPG?

That's two to three years away from having a new book? Outside the Zine. Or the one shots. Or the History of Sentinel Comics book, which has occupied all the SCRPG development time over the past four years.
