Since White Wolf has reverted the rights to Ravenloft back to WotC, does that mean WotC will be publishing Ravenloft books? Or will WotC just let Ravenloft wither and die? 
They'll do whatever it takes to milk as much money as possible out of it. Probably linking it to their Heroes of Horror accessory to boost its sales.
They've already started, if you weren't aware. Take a look at this:

And, no, we don't know what it will be exactly. Probably a big adventure like RHoD.
Best guess?

Ah, yes, those evil moneygrubbers at WotC who actually want to earn a living. ;)

The catalog's out, and it's confirmed--a 224-page superadventure.
They're also reprinting three of the novels in trade paperback format over the course of the year--Death of a Darklord in July, Vampire of the Mists in September or October, and I, Strahd in December.
