It looks like we’ll be getting the World of Warcraft 3.0 content patch with most of the nifty WoTLK stuff in just a few weeks. Quoted from the official post:

We have outlined some of the larger features scheduled to release with the patch below:

New class spells and talents
Stormwind Harbor
Barbershops in capital cities
Zeppelin towers outside of Orgrimmar and Tirisfal Glades
Two brand-new Arenas featuring challenging new layouts, terrain hazards, and moving obstacles
Guild calendar
Hunter pet skill revamp
New profession: Inscription

As mentioned above, this is not a comprehensive list, just some of the major highlights. We’ll post the full patch notes as soon as they’re available. Regarding Inscription, please note that all Burning Crusade players will be able to select Inscription as one of their two professions and level up to a skill level of 375 with it. Upon the release of Wrath of the Lich King, players who purchase and install the expansion will be able to continue leveling in Inscription and the other professions beyond 375.

It’s cool that we’ll have all this new stuff to play with, and I plan to go inscription on my new mage right away. My advice for you: Go buy herbs right now. Inscription uses herbs, and everyone is going to want to play with it. The prices are going to shoot up right before the patch hits, so get them now.
