Does Spelljammer have level 1 Feat equivalents? Also if Ravenloft is compatible, Theros is. I'd say the Gifts in both are a fair bit stronger than the L1 Feats here, and the "any Feat" alternative definitely is, but I guess anyone starting a new RL/Theros game post-1D&D would be naturally restricting PCs to L1 Feats!
My expectation is more that Dragonlance and Planescape will be strongly compatible, and that the others are sorta-compatible. I definitely expect Planescape to be 100% designed "as if for 1D&D".
Probably.
I give very strong odds that they try and make the FR look a lot more jolly and modern and Exandria-esque than in previous editions. Not complaining, just commenting. We won't have the brooding and mysterious FR of earlier iterations (to be fair SCAG was already headed away from that).
Probably not but see above. Well Exandria might, but likely non-official.
My main hope is NEW SETTINGS. It's been nearly 20 years. We know WotC has created, gone pretty far with, and discarded at least two, possibly three new settings in Ray Winninger's tenure alone (and I would imagine several more didn't get that far). I'm a little concerned they might have their own bar too high, but hey it's their company.
I honestly do think 2024 may well see a new setting, but even if it doesn't, I really hope 1D&D has at least two new settings in the time it exists.
I also think what WotC has realized is, ironically enough, as they move more towards lifestylers and collectors, that setting books don't really cannibalize each other, so long as you take a "one and done" approach (not the "spam followup material" approach of TSR), that a lot of people just kind of mindlessly buy them, especially if they have PC options/monsters in them. So I suspect we'll see a pretty steady stream of setting books.
I could be wrong but I don't expect more "MtG in D&D" stuff any time soon - rather MtG is just eating D&D and any other IP it can get its hands on (even WH40K!!!), and so the direction of travel will be more that way.
I disagree with
@Whizbang Dustyboots that Doomspace doesn't give us
any insight re: Dark Sun. I think it does, I don't believe an artist just "placeholdered" Athaspace, that's too specific and weird. But equally I don't think the actual "setting" of Doomspace tells us much. I think all we know is WotC was considering just dropping Athas into SJ, and then decided against. I do think that means we can expect a more "traditional" Dark Sun, albeit a cleaned-up one (no Muls, or they'll be not "bred hybrids" but something else, for example, slavery downplayed or changed to indentured servitude, etc.), and I also suspect it's not going to be out soon. The level 1 Feat thing makes Athas easier of course, as you can hand out Wild Talents etc. that way. And I think this bodes fairly well for a Mystic/Psion class. Oh and probably revised "Psionic subclasses" for a bunch of classes which will fit with the updated 1D&D versions of those classes.
