According to this WorldofWar story, Achievements are definitely going to be added to World of Warcraft, as Blizzard has now confirmed.
“While Wrath of the Lich King will improve many of World of Warcraft’s existing features, it will also introduce plenty of brand-new ones to keep the game fresh and interesting,” said the company in a blog post.
