Here we have a rumor about a rumor, as Marbridge Consulting reports having heard that Blizzard is investigating whether Blizzard China is the source of the recent document with what are allegedly release dates for Blizzard's upcoming games, attributing the rumor to "an industry source." They also say: "The source stated that the leaked internal documents also contain player numbers, revenues, advertising budgets and detailed promotional plans for all Blizzard games worldwide."
