New class confirmed, the Witch Doctor.
* Witch doctor can cast out locus swarm, which spreads between targets and deals damage. Can summon mongrel things that he can cast locust swarm on, which buffs their damage. Outdoor environment now. Quite pretty in that vibrant, slightly cartoonish Blizzard graphical style. Like with StarCraft 2 and it's similarities to the original, Diablo 3 looks and sounds, at least at a glance, quite similar to previous games. Witch doctor also has a mass fear type of ability.

* Witch doctor using a fire bomb spell. Can summon a wall of zombies that stays stationary, but the zombies in the wall flail their arms and do damage to their oponents.
Diablo III is being developed as the definitive action role-playing game, and a true continuation of the Diablo series. Players will create a hero from one of five distinct classes, such as barbarian or witch doctor, each equipped with an array of spells and abilities. As these heroes adventure through rich and varied settings, unraveling an epic storyline and engaging in combat with hordes of monsters and challenging bosses, they’ll grow in experience and ability and acquire items of incredible power.
The game takes place on Sanctuary, a world of dark fantasy. Unbeknownst to most of its inhabitants, Sanctuary was saved some twenty years ago from the demonic forces of the underworld by a few brave and powerful heroes. Most of those warriors who directly faced Hell’s armies -- and were fortunate enough to survive -- went mad from their experiences. And most of the others have buried their haunted memories and pushed the horrors from their thoughts. In Diablo III, players will return to Sanctuary to confront evil in its many forms once again.
Diablo III will be a fitting sequel to Diablo II, with the easy interface, fast-paced action, and visceral gameplay that Diablo players have come to expect and enjoy. It will also include many new features that will take the Diablo action-RPG experience to the next level.
