Ghostcrawler has just posted a response regarding head enchants (not relevant to professions) being removed in Mists of Pandaria. But this little nugget at the end of the post IS relevant:
"Shoulder enchants can now be provided by scribes, so those still exist, but they are also not part of the faction reputation system."
Now I can't be certain, the way this is worded, but it sure sounds like Scribes will be able to make shoulder enchants for everyone. This doesn't specifically state how they will be provided, I'm simply assuming it will be an item similar to enchant scrolls or armor kits. If so, it would be a new item type for Scribes AND a welcome consumable. I gotta say, I think this is pretty awesome for Scribes :)
Let me remind everyone that new Inscription recipes are not in the Beta so we don't yet know what's in store for the profession. But we now know that at least one new product type is on the table. You can read the full posting from Ghostcrawler here.
