This trailer profiles the Witch Doctor class in Diablo III, Blizzard's imminent action/RPG sequel (thanks Ant). The clip shows concept art and gameplay footage while an imposing voice over explains the Witch Doctor's powers to cause illness (hey, at least he makes house calls!).
It's by no means a bad class and will likely be one of the stronger candidates for deeper progression in to Inferno as other have said due to the utility it can bring.
However, I have to say that I'm not particularly sold on this class but that's simply because in any game such as this, I tend to favor the melee-class where I can be in the thick of things to bust some skulls.
While this is not the Necromancer of old, it'll fill that niche quite well and if I were to make a range class, this will likely be it.
It says on your chart that you're fucked up. Ah, you talk like a fag, and your shit's all retarded.
