Oh, I think they have the how and the what figured out, but the question is when. Mearls laid out a whole plan on stream last year, and it would work similar to the Setting books they've already done. They have a two-year development cycle, and I expect we'll see it sooner rather than later.Well I do think there’s some element of nostalgia for all the settings. But I would also agree that Dark Sun has something different to offer thematically when compared to a lot of the more traditional settings like those you mentioned.
I think that when it comes to Dark Sun we’ll see a book when they’ve figured out how to present it in as multi-purposed a way as possible. Like, a psionics primer, Tyr gazetteer, Athas monster manual, and adventure path. Some kind of mix to appeal to as many people as possible.
We’ll see. Eventually!
