Gaming is fun, and fun is for everyone
Winninger has clarified on Twitter that the revisit is a 2024 product, separate from the 2 new classic Ssttings in 2022 and 1 in 2023. The timing of 2024 suggests to me that the revisit may be Greyhawk, revisiting after Ghosts of Saltmarsh.
Can I see the tweet? I didn't know it was 2024, if it is that far out I indeed could see it as either FR or Greyhawk. I too may lean on it being Greyhawk, as that is the 50th Anniversary, and Greyhawk is D&D's first setting.
