From GameWatcher: “World of Warcraft Classic’s Character Clone service will have its price reduced, Blizzard announced today. Set to be introduced with the Burning Crusade expansion pre-patch, it allows players to pay in order to keep playing a character on both Classic and Burning Crusade servers. The two will be separated once the expansion launches.”
