The beta servers for Wrath of the Lich King are down , ladies and gents. That's because they are about to unleash a new build, and you bet this is but the calm before the storm.
As rumor would have it, based on the Gamona video interview at Leipzig earlier today, the level cap will be raised to 80. We cannot know for sure until the servers go back up. The downtime is expected to run for about six to eight hours, which started at 2:30PM PST.
