If they make just new domains, then people would complain that they are reinventing Ravenloft by ignoring the old stuff. Especially because the new domains would have to all be Islands or Clusters, or a brand new Core, in order for it to fit into the world physically.Most of the lore changes. A couple of the reimagined domains were decent to good, but I really believe you should be making new stuff instead of radically altering existing material and using the same names.
If they make new domains and include the old domains, then many of them would be very redundant. And it's likely that the new domains would either be seen as pale imitations of the older ones, or would be seen as better, or at least cooler.
If they make the old domains and don't change them much, just update the stats, then there's absolutely no reason for any fan to buy the book, since we already have some or all of the 2e and 3e stuff. Converting things from one edition to another is pretty easy. Heck, I know that I was very much on the fence about buying anything Ravenloft for 5e, even though it's my favorite setting, until I found out that they were reimagining it.
And if you keep the old domains as-is but remove or improve the problematic things. Take Dementlieu. d'Honaire's entire shtick is basically mind-controlling people, especially women. Sure, it doesn't work on women he's actually attracted to, but I think it's obvious that he doesn't limit himself to just those he actually wants. Especially in the type of society that has a serving class and looks the other way if something bad happens to them. Or take Valachan. It was a domain of kind of simple, backwards, low-tech dark-skinned people--the only dark-skinned people in the Core--ruled by a dark-skinned, bestial were-vamp who murdered a new wife each year. These places are both flavorful, sure, and I liked them. But are they type of flavor that really needs to be continued? Removing the problematic issues from the domains would leave flavorless nothing left. Any surprise that they got changed?
