Patch 5.2 has added a set of class-specific weapons with racial themes!
Each weapon has 4 different colour schemes, but I've only listed one of each to save space. I have no idea how these may be obtained or even if they're going to be used in the game at all but Blizzard generally do not create icons unless they plan on the items being obtainable by players.
Some of them are a bit.. meh in my opinion but the rest are quite cool.

Icons:
So far I've found:
Worgen Death Knight 2h Sword
Orc Warrior 2h Axe
Draenei Paladin 1h Mace
Dwarf Hunter Bow
Troll Shaman Fist Weapons
Tauren Shaman Fist Weapons
Night Elf Druid Staff
Goblin Rogue Daggers
Undead Rogue Daggers
Blood Elf Mage Staff
Human Priest Staff
Gnome Warlock Staff
Pandaren Monk Staff
A generic Gnome Axe
Blizzard continue to add more and more with each PTR build.
