Perculia at the Wowhead Blog posted a summary of the changes coming to professions in Patch 5.2. I’ve narrowed the list to items of particular interest for hunters:
Archeology
- One of the two rare solves for the new Mantid race is a BoA gun: Sonic Pulse Generator.
Jewelcrafting
- Jewelcrafters will now be able to create uncut Primal Diamonds (previously available only from alchemists’ transmutes). Design: Primal Diamond is a world drop.
- Jewlecrafters will be able to create a new item: Serpent’s Heart. Serpent’s Heart contains a rare-quality Pandaren uncut gem and also a very low chance at the two battle pet designs. Design: Serpent’s Heart is a world drop.
Leatherworking
- Pattern: Magnificence of Leather and Pattern: Magnificence of Scales are new world drops in Patch 5.2 that allow Leatherworkers to create Magnificent Hide. Recipes for 5.2 raid epics and new Crafted PvP gear may be learned when making Magnificence of Leather or Magnificence of Scales. The crafted PvP sets look identical to the ilvl 458 Dreadful Gladiator’s gear that was purchasable with honor in 5.0.
- New crafted ilvl 522 gear
- New crafted Dreadful Gladiator gear
- Leatherworkers will also be able to craft the 36-slot Magnificent Hide Pack.
Tailoring
