I was just browsing WCM and found this video on the new (leaked) tier gears.
From the video creator:
1. Blizzard has only added in Priest, Warlock, Mage, Rogue & Hunter Tier Sets.
2. They are under the file names of (example) Helm_Robe_RaidPriest_G_01_HuM.M2
(“G” = Tier, A=Prophecy, B=Trans, C=Faith, etc)
3. Mage helm does NOT work yet and Mages (by the looks of it) do not get robes this time around.
4. I apologize for the missing particle textures on Hunter helm & shoulders.
5. I apologize for the crappy quality, it would have been much better but Sony Vegas decided to give me errors about the video size.
6. Please enjoy.

Lol mages get pants for once? Nice find
