I am sure there will be new gems, and some old cuts changed to reflect the new changed stats. Profession levels will be raised to get new cuts, and I hope they change how you get them. Jeweler's tokens were a PITA
Alchemy

New elixirs will be about 75% as strong as flasks. So you can get more total stat points with two elixirs, but flasks will still be the best at giving you a single offensive or defensive stat.
New unique material used by nearly all high-level recipes will be created by alchemists on a one-day cooldown.
New Mysterious Potion created with common materials restores health and mana in a massively random range, as well as sometimes granting the benefit of another potion. The health and mana range is from 1-20,000 and is able to crit. The minimum amount restored, however, is scaled upwards by the Alchemy skill, making it a great choice for alchemists to keep for themselves.
All potions and elixirs now use the same basic vial type. Flasks still use a fancy vial.
New Alchemist Stone

Jewelcrafting

Some gem colors have changed! Hit is now blue. Mastery and Dodge are yellow. Intellect is now red. These simple changes have created a much more diverse matrix of gem cuts.
New Jewelcrafting dailies will be introduced.
Many cuts are being added to support the new Mastery stat.
Some new Cataclysm jewelry recipes have completely random properties, and can sometimes create superior and epic versions.
Jewelcrafters will have some fun new (and potentially lucrative) vanity items, including fist weapons, rhinestone sunglasses, monocles, and stardust (sprinkle on players for entertainment).
