Blizzard have finally revealed the third Diablo 3 character - a Wizard. As far as I can tell from the gameplay video and the class description, it looks like a copy&paste of the good ole Diablo 2 Sorceress.
The Wizard skills revealed thus far are:
* Disintegrate - constant ray of energy going through multiple enemies
* Electrocute - chain lightning
* Teleport - blink about half a screen away
* Magic Missile - single target damage spell
* Slow Time - creates a sphere that slows down projectiles (very similar to the Protoss Mothership skill)
