Here is something I'm nervous, but mostly excited about. The resurrection of the Ravenloft line of novels. The actual D&D sourcebooks were abandoned by TSR/WotC some years ago, then were picked up by White Wolf (who actually did some very cool things with it), then it was abandoned again. Ravenloft is the proverbial undead setting.
WotC then went and republished some of the Ravenloft novels whose authors are bigger names now than they were when they wrote these books. That seemed to be the end of it, but now new novels. For anyone who's a Ravenloft fan, that's a really big deal.
The first book will be coming out in March of 2008, written by Ari Marmell (who's done some excellent sourcebooks for Eberron, among others), and will actually involve Earth. That's a new direction for Ravenloft.
