Note - For the more recent October 2008 Inscription post click here. Otherwise - the rest of this post will tell you what we knew about Inscription BEFORE it was released.
The following are a collection of quotes I've been able to collect regarding the new World of Warcraft Inscription Profession:
From the Expansion Press Release:
"Inscription" Profession: Learn this exciting new profession and gain unique ways to permanently enhance spells and abilities in the game.
From the Expansion FAQ:
What can you reveal about the new profession coming with the expansion?
The Inscription profession will allow players to permanently enhance their own spells and abilities and those of other players. You can think of it as enchanting for your spells and abilities. We'll provide more specific details on the mechanics of this new profession in the months ahead.
From the WoW Insider Liveblogging Post on Professions and Items:
Q: Will Inscriptions be like enchanting or have items for Ah? same with dying armor?
A: No plans to dying armor. Inscriptions will be items.
Q. Inscription system -- will switching to it mean having to do noob things to level up?Examples:
A: Inscription - haven't determined how it will work out. Been brainstorming how to make all professions easier to switch to for higher levels.
From the WoW Insider Liveblogging Post on The Wrath of the Lich King Demo:
Inscription example: modify existing spells and abilities. Fireball, for instance, can inscribe it to perhaps have knockback or further damage.
From Kotaku's "More Details" Article:
Wrath of the Lich King will introduce a new profession called Inscription that will let players customize individual spells and abilities in their spell book -- to change the cooldown timer on a Fireball, for example, or alter the crit rate of a healing spell.
With the announcement of the Inscription profession, there's still a lot of information left to be conveyed, so Blizzard shared a few tidbits with the audience. This new profession will allow for people to imbue a characters spells and abilities with an extra zing, almost acting as a single talent point for each of your abilities. Whether it's sinister strike, multishot or a frostbolt, you'll be able to tweak every last ability. Inscribers will also have a new ability that hasn't really been talked about before, allowing them to create completely new items. Though the panelists couldn't talk about it just yet, there will be a whole other side to inscription rather than just altering your spells and abilities. When it comes to inscribing abilities for other people, the inscriptions themselves will be scroll based, so players can put up an inscription scroll on the auction house, allowing others to buy and upgrade their arsenal at their leisure.

New Profession: Inscription
Burning Crusade introduced Jewelcrafting, which allowed players to customize their gear; Wrath's new profession, Inscription, lets you customize the abilities and skills in your spellbook. "You're permanently changing your spell kit," says lead game designer Tom Chilton. "You might find a couple different recipes to inscribe your Fireball with increased crit chance, or increased damage, or faster cast time, or lower mana cost -- so it's almost like a talent system within the profession system. Only it's more based around choices you make for an individual spell rather than affecting your character as a whole." Unlike Enchanters, Inscribers will be able to sell physical product (creating tradeable "scrolls," for example, from ink, paper, and other reagents). Only a handful of core spells will be customizable in this fashion. Don't expect to extend the range of your Priest's Mind Vision; do expect to extend the duration of your Hunter's Freezing Trap.
From WoWBlues - A response like many when forum posters ask for more information on inscription:
I know a lot of people are looking forward to hearing about this new profession, but we have no details to share right now. Building a whole profession from the group up takes a lot of work, especially so since this affects players' spells. A lot of changes and updates would need to occur for us to get it where we want it so until we have reached a point like that, we don't have anything else beyond the small amount of information we've shared so far.
Please continue to be patient and we will discuss information on this when they are ready.
From computerandvideogames.com(via WoWInsider):
"The idea behind it is to give players even more specialisation options beyond the talent trees," explains Kaplan in a manner that would bamboozle the WOW-phobic to death." As a possible example, a mage could have their Frost Nova enhanced for either greater range or longer snare duration - our intention is to provide viable options rather than one 'best' Inscription for each modifiable spell or ability."
