Yeah, I've heard the same stuff. The LAST thing we Hordies need is our own race of elf. Blah... damn elves. They multiply like coat hangers.

After reading through some of this stuff it doesnt seem real, however I think we will have an announcement about the expansion within the week what with BlizzCon going live on the 29th. And the Expansion is going to be playable there, so they will want to get the word out.
