The team over at HomeLAN has put together a set of questions regarding the upcoming Throne of Oblivion expansion, and Shadowbane producer Frank Lucerno was kind enough to answer them.  Here's a sample:

HomeLAN - What can you tell us about the new playable Vampire race at this time? Frank Lucero - Our goal with the Vampire race was to create a new kind of gameplay experience that just wasn't a rehash of some existing race with some stats juggled. As such, Vampires have some unique strengths but some unique weaknesses as well. First and foremost, all of a Vampire's spells and abilities will cost just health - mana and stamina will be near useless for them. Vampires only have one resource to manage, but using their powers too quickly may leave them weak and exposed. Vampires will also get what we call 'fortitude' powers. These temporary powers will dictate the maximum size of any single blow they can take in damage. Vampires will have weaknesses, though. In particular, healing spells don't work particularly well on them, and they are extremely vulnerable to holy and fire damage.
