Dark Age of Camelot Expansion Details

MMORPG.com has posted a short article that discusses Mythic's plans for another Dark Age of Camelot expansion pack. Here's a bit of what they gleaned during E3:
What they would say is that the new expansion, which will be officially announced soon, has one new race and one new class. Anyone, from any realm, can unlock the class on an account by account basis and then make characters using it. The race comes free with the expansion.

They plan to launch the expansion on their 5 year anniversary later this year.
