Debate fuels my Fire
Although the big takeaway of the "Inside the D&D Studio" roundtable was that three classic settings are being looked at, there were other tidbits teased in that interview. One that stood out to me was at timestamp 10:49:00, where Ray reveals that they are planning to release new types of products, specifically designed to work with creators on the DMsGuild and other folks who are producing really creative work. They even mentioned that these are anthology products including shorter adventures.
This sounds way too similar to the product Welch once teased with adventures published by DMsGuild writers, and other including Deborah Ann Woll and Marisha Ray. They're almost certainly the same thing, even though the actual adventures/writers chosen to go in this anthology may have changed since.
