In order to sway people to attend its fanfest Blizzcon, World of Warcraft developer Blizzard is offering attendees a bunch of swag (free goodies) to be announced at a later date. It did, however, already confirm that a beta key for an upcoming Blizzard game will be provided, as well as World of Warcraft in-game murloc suit, an item that can be redeemed and given to your favorite WoW character.
