There has been much anticipation for the World of Warcraft 3.1 patch to go live and sources say that it shall be released sometime soon this week. This patch is the biggest update since the Wrath of the Lich King expansion debut. Sources say it is set to go live today, April 14th.

The patch is currently on Blizzard’s download servers and according to MMO-Champion, it could be just a matter of hours before the official word.

The patch contains numerous changes and additions including the new Ulduar instance. 

For millennia, Ulduar has remained undisturbed by mortals, far away from their concerns and their struggles. Yet since its recent discovery, many have wondered what the structure’s original purpose may have been. Some thought it a city, built to herald the glory of its makers; some thought it a vault containing innumerable treasures, perhaps even relics of the mighty Titans themselves. Such speculations were wrong. Beyond Ulduar’s gates lies no city, no treasure vault, no final answer to the Titan’s mysteries. All that awaits those who dare set foot in Ulduar is a horror even the Titans could not, would not destroy, an evil they merely… contained.
