Inscriptionists? Are people really still calling them that?

Everyone knows they're called inscribers or inscriptionators.

I also have a feeling Inscription will continue to be a big money-maker, but it will be more complex. Between glyphs, dust, off-hands, trinkets/darkmoon cards, books of experience, the patterns you mentioned, and the fortune cards, along with selling raw inks and pigments, scribes now have even more ways to make money, but no longer can you just use quick auctions to post a zillion glyphs to do so.

Basically it seems to me that scribes will still be able to make some big gold in the next expansion, but it will take more thought effort as opposed to setting up a simple assembly line for your gold stream.

Also, it's Scribe. Okay? Scribe. I consider Blizzard to be canon on nomenclature, and it says it all right here:
http://www.worldofwarcraft.com/info/professions/inscription.html
"Added with patch 3.02, “Echoes of Doom,” the Inscription profession allows its practitioners, called "scribes," to enhance the spells and abilities of players’ characters..."

Sorry to be a bit picky about that little tidbit, but I've seen it called other things, and have seen debate on it. By canon, you are not an inscriptionist, scrivener, inscriber, or any other permutation... just scribe.

So...it's not Inscriptionatrix?

BRB, dropping Inscription. :(

Inscriptinomitron.

The mysterious fortune card will be used in cooking top-quality food, and can also just be used to create a piece of vendor trash with a random value up to 5k gold. There's also a number of useful consumables, including stuff like "gain 10% bonus XP for the next hour", that will sell like hotcakes. And there's the reclamation.

Glyphs will continue to sell a little. Quite frankly, it's the scarcity of glyph-makers that accounts for at least 50% of the glyph's value. Glyph of Felguard sells for 50g or whatever because there's only four people on the server who can make it (randomly gained recipe) and two of them can't be bothered to post them, they just learned all the patterns to have fun. So I think that, if the glyphs still have to be learned by research/books, the market will maintain enough scarcity that we will still see reasonable income from that part of the market.

Depends on the server of course, but I definitely move a lot more hunter, death knight, and paladin glyphs than the rest of the classes, and my research (looking at who buys my glyphs) indicates that a fair number of these are for alts and other new toons. So that level of demand will remain as well.

@Pyro: "Between glyphs, dust, off-hands, trinkets/darkmoon cards, books of experience..."

Whoa, whoa , whoa, wait a minute there. Books of experience? Scribes can make items that give experience now?

Scribblers. There, ended the debate for everyone.
