Gaming is fun, and fun is for everyone
Right...but the new to 5E classic settings are not the revisited 5E setting. They're separate things. They specified that the revisited setting was one they already did for 5E. So they're revisiting a setting that already had material published for it in 5E. That doesn't mean it has to be a setting book. This qualifies. A cameo is a small, walk-on appearance. This doesn't qualify. A full book about one setting isn't a cameo. This is a revisit to a setting they've already published in 5E.
Winninger has already confirmed via Twitter that the setting revisit is happening in 2024, so this is not that either.
