All the new Vampire Counts Army List 2008 edition magic items and powers can be found in the link below.
Note: this is a rumour which was posted by someone on Warseer who claims to already have the army list - there's no way of knowing for sure until the book hits the shelves but in case you're interested then visit the below link to librarium-online. The best thing to do is just buy the book when it comes out :)
