New Encrypted Back Pieces Added to Retail WoW - Possibly Related to 10.0

wowhead.com:

Blizzard pushed a new build to live servers last night that added five new encrypted 3d back pieces to the game. Let's take a look at them. Data shows that the back pieces all use the same model, 61908, only being different recolors each.

These 5 back pieces are locked behind the same encryption key as the previously datamined mount and pet, which are likely tied to the Digital Deluxe bonus of the next expansion. The mount from the bundle is linked to the 9fx_drakemountemerald_buff_4219045 spell and has Emerald Dragon spell effects attached to it. Could these 5 3D cloaks be cosmetic dragon wings? Having five different cloaks means it could be that each is themed after one of the five dragonflights.

Sadly, this is just speculation, as we have no way of knowing what these encrypted files are until Blizzard unencrypt it. We will likely know more about them next Tuesday, April 19th, when Blizzard has their presentation about what's next for WoW at 9 am Pacific Time. Thanks to MrGM and Simaia for finding out more about the back pieces.
