Blizzard has posted a huge preview about Ulduar today on the official site. Hopefully this means that it will be released very shortly, as many raiders have long since finished the current Wrath of the Lich King content and are eager for more.
As the next step in tiered raid progression in Wrath of the Lich King, Ulduar is set to let players enjoy gorgeous setpieces, sprawling battlefields, and innovative boss encounters. Ulduar's design aims to provide a fun, unique, and innovative raid experience, and it includes additional challenges and rewards for seasoned raiders.
In this sneak-peek at World of Warcraft's newest raid dungeon, we'll take a look at some of the new content that makes Ulduar stand out.
You can find more on the official preview page.
