If you haven't already heard the rumors of two new possible playable races the 'Worgen' and 'Goblin' that where found in the 4th PTR Build. Blizzard has added these two new racial Halloween masks to the collection. You might think "oh there just masks! doesn't mean Blizzard is making new races to play!" But you could be right, thou if you think about it all the current Halloween masks are ONLY of playable races. Maybe Blizzard is just trying to spice things up a bit by adding in new masks for this years Halloween event. I just hope thou if added that the Worgen would be playable by the horde faction (Doubt it). If Blizzard does plan on adding new races and with the rumors of the next upcoming expansion 'Cataclysm' i do hope Blizzard plans to add a few more character slots per realm.
