Patch 4.1 just went live yesterday and Blizzard has already posted two preview videos for patch 4.2. As Blizzard puts it, "Feast your eyes on the adventures that await when World of Warcraft patch 4.2 takes you through the fire and flames and into the Firelands."

Once you watch the videos below, you should listen to some Dragonforce to get pumped for the next update. I don't know about you, but that's the first thing I thought when I read Blizzard's comment.
