An update on the new classes from EA:

"You may have already noticed that we have opened up the last 7 events for the Heavy Metal Event so you can take part in them all, at your leisure, over the extended Thanksgiving Holiday.  We want everyone to have a chance to unlock the Black Guard and Knight of the Blazing Sun. You can now finish the event and redeem the Heavy Metal Chest from a Herald.  When you redeem the chest, it is important that you open (right click) the chest so that you become eligible to play the classes a week earlier than everyone else.  If you qualify through the Heavy Metal event, the Black Guard and Knight of the Blazing Sun will become playable next week when we do the 1.0.6 patch.

See you in the WAR!"
