That said, I do hope that not all the domains are presented with the "weekend in hell" default. All my best RL campaigns were played with natives, rather than visitors.
So long as there's at least the occasional nod to playing natives--even if it's only in one out of every handful of domains--I think it can work. But if Ravenloft is reduced to just a "not-so-nice place to visit," I think it'll be a missed opportunity.
Ari, get to work and pitch some things to Chris!

I suspect that the majority of domains will be presented as a weekend in hell, but that there will be nothing to prevent you from playing a native, except that being a native of Sunderheart, for example, would really suck.
