Original 6 warcraft 3 races?

[flashbacck]

There were originally suppose to be 6 races iin warcraft 3. Obviously 2 ended up being dropped. What were the dropped ones? One was the demon race, what was the other?

all of the original 6 are still in the single player game, but only 4 are playable now..........one was just too powerful, I don't recall what the other race was....the powerful race is the new threat to everyone in the single player game...

The taurens were the original race but i think they got canceled for another race later on, and the demon burning legion is the supreme power evil race.
