I'm wagering that they aren't touching some of the more beloved domains/darklord (maybe not: See Mordenheim) but the ones getting overhauled aren't the ones that were especially beloved: I don't think you could poll most fans of the setting for favorite darklord/domain and get d'Honiare or Van Karkov as answers.I don't deny that some elements of Ravenloft were going to need an overhaul. I understand that perfectly, in fact. I'm no purist. But I think you may be missing the point I'm raising.
If their goal is to make Ravenloft work better for new audiences, then why revive these old, problematic domains at all? Just take the concepts and create a brand new domain, without any baggage whatsoever.
If they're trying to hook older fans, you'd think they'd want to keep as much of these old domains as possible, while limiting fixes to the problematic elements. (And if the domain just plain doesn't work without the problematic elements... let it stay in the past.) If Wizards thinks that all you need to satisfy older Ravenloft fans is a few familiar names, then they must think older fans are very superficial...
I also think WotC called out the biggest changes early to get ahead of this, I'm thinking there will be a lot of domains that have only minor tweaks or just cleaned up. Some others might not make the transition (Sithicus is a prime example). They called out the most radical changes both to advise "this isn't the old setting repackaged" and to get people used to the notion of these changes so that when they see Mordent, Darkon, or Forlorn is more-or-less the same, they'll be willing to accept the revised domains more.
Or not. We'll find out in a month.
