I've been playing around with the
Diablo III Skill Calculator while impatiently waiting to be invited to the closed beta. I only got a couple builds in mind but I'll add more as I make them.
First one is an idea for a Barbarian Tank, second is a Monk Healer build. (Is there a way to place uploaded images inline?)

EDIT: Wizard Cold Nuke Build added.
EDIT EDIT (10/19/11):
Demon Hunter - I was going for a balance between skills that generate hatred, skills that cost hatred, and skills that cost discipline (there doesn't seem to be any way to generate discipline through skills but they are relatively inexpensive to use). I tried to concentrate on big area damage with slow effects. The passive skills regen life or enhance my damaging skills.
Witch Doctor - Basically a summoner build with runestone mods that generate mana.
