After reading the details on the Dragon Lord campaign, for some reason it doesn't sound quite as appealing. I'm getting a claustrophobic feeling, everything is in one big mountain?
The drow campaign actually does sound intriguing, aside from the cliche "drow invasion". Maybe it's because of the promise that many of the PCs' choices will effect the outcome of important events. I get the feeling that the hook to get the party together is really bad, please don't tell me it's "you are each teleported to this remote island". Lame. I love the idea of a sweeping plotline from 1st through epic though. I will definately thumb through the book at the FLGS.
