New Hairstyles in, although it seems recycled mostly from other races. Examples for Draenei:

Also it seems that Death Knights will have their own hair colours and skin tones, making them look more "dead" (a few of the skins look really ugly, especially the draenei and gnome ones). Example:

Wrath of Air is now 5% spellhaste instead of 10%.

Lastly, it appears the glyph interface has been changed to 3 Major and 3 Minor glyphs, seems cosmetic glyphs have disappeared (?):
