There are two specialties within the Shadow Warrior career-- one is all about increasing ranged damage as much as possible, and the other is about adding a little bit of melee effectiveness at the end of all that ranged damage. They make it super clear that it's only a little bit of melee-- as you can see from the still above, Shadow Warriors love their bows: "bow bow bow bow bow." But one tree of the Shadow Warrior class will let you finish off foes with melee, adding a little extra dimension to what is primarily a ranged class.
There's also just a tiny bit of game video in the podcast, but way too little-- they even say that they couldn't get much approved to show off yet. At any rate, this looks like yet another interesting addition to Warhammer's already mixed bag of tricks.
