In a great April Fools prank (I hope) World Of Warcraft has the Bard class up; which is played Guitar Hero style with your pimped out Guiter-Keyboard.

The deeds of every great hero inspire countless songs of triumph, virtue, and epic adventure. But although a hero’s glory endures in song, the creators of those songs are seldom remembered. After ages spent singing of the heroic exploits of others, the bards of Azeroth are finally stepping into the spotlight on their own terms, proving once and for all that while just about anyone can pick up a sword or cast a spell, only a true hero can vanquish evil with the power of ROCK!

Its very well done, so go enjoy it
