I figured I'd ask in a new thread so I don't have to go and re-read all of the threads. I remember someone saying that Strahd's castle will be a lot like his castle in I6, with most of the new material being the castle's environs. Is this confirmed? I think this would be a good approach; tweak and polish the original I6 (add to it where necessary), and dedicate most of the new material to fleshing out the surrounding territory. It would also be good if they designed it so that, say, a 7th level party could play the adventure by skipping the environs and going straight to the castle.
