Ravenloft already has a well-received hardcover in Domains of Dread; the 3E version is also hardcover, but suffers from the decision to spin off "DMs only" material into a supplement.
If they do ravenloft i think they shouldn't underestimatethe appeal of the black boxed set DoD is great in that it offers a more complete setting but does lack some of the atmosphere (not to mention fabian art) of thered and black sets.
Here is what I would like to see re-released:
All the van richten books (these are the best supplements ever imo)
A mega boxed set that combines the red and black
Castles Forlorn boxed set
Feast of Goblyns (in the original format)
Print the rest of the hyksa modules as one book
