On the Aeria games website and not the Eden Eternal website. There has been an announcement for Ursun and Halfkin Patch that is coming soon!
The announcement should be right on the front page stating:
"Champion the tall and fierce Ursun, or befuddle your enemies as the small and cunning Halfkin. Enjoy their unique ability to craft valuable tools to aid you in battle. Ready yourself for new maps, new quests, a new class and much much more!"
As of now there is a "More" Button you can press to take you to a new page to give you more detail, but right now it doesn't seem like they have everything ready. The "More" button just takes you right to the Eden Eternal website.
