The official announcement reads the following:

Armed with a trusty axe, killer riffs, and a ton of attitude, the guitar-wielding bard is the second hero class to be introduced in the upcoming Wrath of the Lich King expansion for World of Warcraft. The bard excels both as a solo performer and as part of a solid group lineup, able to front in a number of roles as varied as his musical repertoire.”

The bard’s fighting ability will be based on his extensive Metal skill line, which grants him the transformational ability "I Am Murloc" or direct damage effects like "Epic Solo".

Also on the list there’s the bard’s Punk tree, which can support the party with a wide range of abilities, such as "Nonconformity," (dispels fear, mind control, and the like) and "Mosh Pit," (gives a boost to the group’s movement speed while its members stay within range).

Blizzard announced that a special .new guitar-based keyboard peripheral, set to ship alongside the Wrath of the Lich King expansion. A special Frostmourne-themed axe will be sold separately, Blizzard claims.

Last but not least, don’t forget that today is April Fools’ Day.
