For those of you who have not yet seen the new trailer for patch 2.4, "Fury of the Sunwell," I recommend that you go see it at the WoW in development page.
As nice as the 2.4 trailer is, however, I prefer the, "real," 2.4 trailer, created by Beckman Movie Productions, the creators of the very funny Azerothian Super Villains series. You can find their version of the 2.4 trailer here and their youtube channel, where you can see the rest of their works, here. Enjoy.
For the Horde and the Naaru!
