Gaming is fun, and fun is for everyone
Salt Marsh is no more a setting book then Curse of Strahd was and they never referred to VRGtR as a revisit, just as a classic setting, so it had to be a classic, none MtG setting book, that has received somekind of none adventure setting book previously in 5e, that left folks unsatisfied. That is FR. And yes I know I've guessed FR before, but I was right about everything except the timing
I mean, you haven't actually been proven right yet, to be clear.
Don't get me wrong, I think 2024 could still have Greyhawk as a nostalgia setting book as well, but Greyhawk isn't the face of D&D anymore, FR is, and Greyhawk hasn't been for a long time, so FR is pretty much a lock. Plus FR gets a new Campaign Setting Book EVERY major or Minor Edition change since it came out, without fail.
See, I think FR being the central setting of 5E works against its likelihood of being a D&D setting. FR gets an adventure book every year that adds more details to it as a setting. I personally feel the D&D 5E team believes they can keep mining FR for adventures, but want to keep using setting books as a method of publishing worlds that will not get that same attention otherwise.
I will reiterate (from another thread) FR is likely the frontrunner for this revisit spot. But I wouldn't count Greyhawk out just yet, it clearly has a lot of fans here and on the D&D Staff (they're as much a sucker for nostalgia as us). And it really is a good candidate in that year due to the 50th Anniversary.
A 50th Anniversary Greyhawk Guide would be super dope, I'd love it! A new FR book would be cool too though.
