I doubt that many RPG writers/designers have actually said that out loud, but certainly their fanbase has, and that's what I was trying to say.
Possibly, but what I've gotten from quite a few people that where extremely enthusiastic about Daggerheart is that way more then I expected didn't enjoy it. None of the Daggerheart related crowdfunding projects has breached the $1 million mark, not by a longshot. The Dungeons of Drakkenheim version for Daggerheart only did ~$460k, which is only 40% of what they did with the original campaign for D&D 5e. Their other three Drakkenheim (5e) campaigns ended all in the $1+ million range. Even the official cards KS by Darrington Press fell short of $400k. Something like Draw Steel did $4.6 million during the KS, and their follow up KS already at $1.5+ million. But it is difficult to say much about the Daggerheart sales. Nor do current sales say anything about the future. The French translation of Daggerheart raised ~€225k, which isn't much imho.
Darrington Press also announced in 2023 'Illuminated Worlds', they used that for Candela Obscura, which they released two years ago, that was the only product for that from Darington Press (Beadle and Grimm did something under license, which is OOP). That webseries has also been on hold for a year and a half.
After almost four years only the Tal’Dorei Campaign Setting Reborn for 5e came out (besides the previous official D&D stuff: Explorer’s Guide to Wildemount in 2020). These products tie in into their webseries, when those end or go on hiatus, interest and support seem to die right along with that. And their current 4th CR season seems to be not set in Tal’Dorei (but in Aramán, a new world) and they're using D&D 5e (2024). As far as I can tell (consulting wikipedia) they've done three one-shots using the Daggerheart system. So unless that changes drastically, I suspect that the hype will taper off quickly. In 10 years some people will play it, pretty sure about that, but there are still folks that play D&D 1e as well...
