On a post today on the World of Warcraft forums, Jeff Kapaln revealed that he's stepping away from World of Warcraft to work on Blizzard's "upcoming, unannounced MMO." Kaplan, who has served as lead designer on World of Warcraft for the last few years and was the game director for Wrath of the Lich King, did not offer any details on the new game or reveal his new role, but he did state that his passion for World of Warcraft is still strong and, in his words, "fuels the challenge of making our next MMO even better." Those are some big shoes to fill, as Kaplan himself admits.
We hope to have more details on this new project in the coming months
