It sure reads to my cynical eyes like spinning FR unexpectedly coming in fourth. ;|
Eberron 'needs' a lot. For one thing, it was always kinda a catch-all setting, with a place for everything that'd ever been in D&D. And, of course, it had it's own new stuff, too. It's magic-as-technology setting could be left a backdrop but would really benefit from a big list of common (on Eberron) magic items that pulled back a bit from the 'just better' 5e philosophy.
Dark Sun also clearly needs some significant adjustments, rules and alternate options to make work, just as it did in AD&D and 3e.
Planescape, for all it's weirdness, maybe not so much.
Seems likely. CoS was a pretty well-received product.
Yes, regardless of topic. But feel free to vent here, anytime, instead.
I opted for politely asking him with friendly smiley faces if we could expect to see an update at some point.
I think Eberron needs only a few things that aren't already out or in that UA article. Just need the UA article material updated, and PC race writeup for some of the volo's races that didn't get them. Like gnolls. Call 'em Eberron gnolls if you gotta. Then we need Kalashtar, a decent amount of new monsters (who doesn't like those?) an article's worth of info on dragons and giants, and the basics of the setting that aren't in the writeup for those options above, the Mystic class, and the aforementioned magic item guidelines.
I think there is room to do a lot more without retreading anything, though. Especially if they call in Keith Baker to have some fun with parts of the setting that haven't been done that much yet.
What I'd most like to see is something like the Ravenloft story, with a "elemental evil player's companion" (built into the adventure book or separate, I don't care), for Eberron, Planescape, and Dark Sun, and maybe for Mystara, Dragonlance, and Greyhawk.
Combine that with a PHB sized book about building worlds, with setting info for each of those along with some alternate rules options, variants, etc as that year's big release.
If each setting opens up in the guild when the storyline comes out, Keith Baker has said that he is eager to put out some new content on the that platform, and I'd love to see it.
Also, Dragonlance used to be one of the most popular fantasy properties around. And Weiss wants to do a rewrite/Unabridge Author's Cut version of the original Chronicles.
And most of these worlds are ripe for cartoons, especially Eberron. An RPG of the Chronicles story from DL would be great, if they could get the right people to do it.
and I think that if they promoted DDO during the Eberron based storyline, Turbine would be happy to build some content to tie in to the story line.
