There are quite a few new profession changes in 4.3 - I've combined them all into one thread with some links for you guys to discuss.
As always, watch the front page for news - the patch is still in the very early stages, do not panic or freak out because of something, wait and see how it develops and at this early stage, although a lot of items have been datamined, their location or detailed information about them is unconfirmed speculation. I will update this as and when we have new information.
Please see Patch 4.3 on PTR for full information.
The new material which most likely drops from bosses in the new raid is Essence of Destruction
Announced: Chaos Orb in 4.3 will be Bind on Equip, and all will be able to roll on them. All existing orbs will become tradeable.
Note: we have no confirmation of where any recipes currently drop yet, but we were told that the Darkmoon Faire would have profession recipes.
Alchemy
Recipes for new transmute epic gems have been datamind, but no one knows exactly where they pop. These recipes are BoP and are likely to have a cooldown - will confirm when we know where and what the mats and the cooldown is (do you think it will share a cooldown with living elements/truegold?)
* Recipe: Transmute Deepholm Iolite
* Recipe: Transmute Shadow Spinel
* Recipe: Transmute Elven Peridot
* Recipe: Transmute Lava Coral
* Recipe: Transmute Lightstone
* Recipe: Transmute Queen's Garnet
Discussion thread on these here

* Vicious Ornate Pyrium Legguards
Some people have pointed out that none of these new recipes require truegold; does this mean pyrium is not going to be as useful as it once was? Or is this because truegold will be sharing a cooldown with the epic gems? There's a discussion on this here.
Enchanting
* Maelstrom Shatter
There is a discussion thread on this and how it may affect market prices here.
Inscription
Inscription has several new glyphs
* Glyph of Shadow
* Glyph of Stabbing
Along with new PvP BoE Relics
* Vicious Eyeball of Dominance
* Vicious Charm of Triumph
* Vicious Jawbone of Conquest
Jewelcrafting
Epic Gems have been added to the game
* Shadow Spinel
* Lava Coral
* Elven Peridot
* Queen's Garnet
* Lightstone
* Deepholm Iolite
Each one is cut with a BoP design. The designs are now up on the PTR as of 14th Oct and are purchased from a jewelcrafting vendor next to the old daily/vendor. They use the same daily tokens. For 5 tokens you can buy a specific recipe, and for 4 tokens you can buy a tome which produces a random recipe (like a book of glyph mastery; but for epic JC patterns). Pure gems are +50 stats, and hybrid gems are +25/+25 stats. Click on the above links to see all the gem listings.
Chimera's Eyes are listed on the PTR as +77 to stats (+10 stats extra per gem) to improve the static bonus. However; Blacksmiths can currently get an additional +20 points if every gem is epic due to the two bonus sockets. Don't go dropping your professions or ranting about it yet though - still plenty of time for other professions to be tweaked accordingly.

Side note regarding Archaelogy / WoW TCG Loot:
As a side note, there has been speculation on whether some new datamined items are archaelogy, but according to the WoW TCG Forums these items are for the new card game expansion decks which are nothing to do with professions but I'll post them here, but it seems unlikely (but nothing's confirmed!) that these are archaelogy items, and include Tome of the Forgotten Kings: Sand Scarab, Spurious Sarcophagus, and White Riding Camel. There are no changes yet confirmed for archaelogy and the above loot is from a spoiler thread on the wow tcg forums.
