4E was the one where they wanted to shift to digital services, but they didn’t ever materialize. (In case you’re wondering why it never happened - I was on the job market in Seattle at the time; they were offering a 60k salary for a senior engineer with a combo of rare talents in the same city Amazon was offering 90k to a junior engineer.)
5E was a reaction to 4E being hated by a large portion of their fans, and then Stranger Things and Critical Role resulted in them lucking into the most successful D&D edition yet, so I think their policy was mostly “Don’t do anything, you might break it again.”
I sure hope so.
Any other RPG breaking out as the biggest one would do wonders for the hobby.
