This is sort of a head scratcher, to be honest.
- It's now 10+ years since initial release.
Why would a 10+ year gap be a head-scratcher for a new release? There is a 10-year-gap between D&D 2014 and D&D 2024 as well as a 10-year-gap between CoC 6E and CoC 7E. 7th Sea was first released in 1999, and it got its second edition in 2016.
- It's been saddled with a massive black eye from one of its original creators.
Who is explicitly not involved. That black eye has also not stopped other creators from supporting Dungeon World.
- There's now a long line of successors / add ons in the same creative space (Stonetop, Perilous Wilds, Freebooters on the Frontier, Fellowship) that are near-universally agreed as improvements to the original.
You will generally not find these games in your average TTRPG store. Even after 10+ years, I could generally find Dungeon World in a TTRPG store here in Germany. (I was pleasantly surprised to find a German translation of Perilous Wilds in my store.) People generally don't know about these other games, which is why people ask first about running Dungeon World. Only then do they hear about these other games.
Stonetop and FotF aren't really games that would replace Dungeon World for me, since the aforementioned games move Dungeon World into more specific niches than Dungeon World.
- Blades in the Dark / Forged in the Dark didn't even exist when DW was first published.
And since then, there's not really a FitD game that fits in Dungeon World's niche of D&D-esque adventure. None of the projects that tried ever really got off the ground. Most of the ones that people occasionally cite are half-finished projects that started shortly after BitD was released but were abandoned thereafter. As it turns out, when this question comes up, many people just recommend playing Dungeon World.
- It's hardly a stretch to say that Ironsworn is treading pretty closely to the same ground as well . . . and Ironsworn + expansions has a larger following than DW at this point.
Does it? Ironsworn has a Reddit community of 10K+ people, whereas Dungeon World has one of 17K+ people. I think that your strong biases towards Ironsworn is clouding your judgment. I also tend to think of Ironsworn more as a solo game, which is why I think that it isn't really covering the same ground.
- Daggerheart is coming, and coming soon . . . and lives in the same creative space . . . and has infinitely more mindshare, audience, and potential backing.
IMHO, Candela Obscura was a bit of a dud that didn't make much of a splash despite having "indefinitely more mindshare, audience, and potential backing." The reality is that Daggerheart may meet a similar fate, especially if their fans just want Critical Role to play more D&D instead. Critters may not want a game in that "same creative space" as Dungeon World. Critical Role cultivated an audience that enjoys Matt Mercer's more traditional 2e D&D style storytelling. They may bounce off of Daggerheart.
Like, I'm a big fan of PbtA / FitD style gaming in general, and fantasy PbtA in particular, and the statement of "Dungeon World 2.0 is on the way!" does absolutely nothing for me.
If it does nothing for you, then move on. There is no harm in a second edition for those who otherwise want it. I think that there is value in having a second edition of Dungeon World to refocus the DW Community. As you say, one of the creators has a black mark. A new edition may be a breath of fresh air for the community, even if it's helmed by Luke Crane.
