They say that they have 15,000,000 subscribers, and lets say roughly they have played a year each, so that is 42.50 x 6 = $255 a year, (2 month subscriptions).
255 x 15,000,000 = 3,825,000,000
Subscriptions = 3,825,000,000
Game expansions, WoW normal + Burning Crusade = $30, Wotlk = $60, Cataclysm = $60
Game Expansions = 2,250,000,000
And some players, lets say 5,000,000 have played about 4 years, so 255x4=1,020
4-Year+ players = 5,100,000,000
Blizzard could have made that much SO FAR, but not exactly that much, as not all 15,000,000 players would have Wotlk and Cataclysm, so they would have AT LEAST have made 10Billion Bucks so far....
What do u guys think????
P.S This is Australian Dollars
