And yet you still dont even understand the basic premise of why the stock jumped. It has very little to do with Blizzard and even less with WoW. If you look at the earning data on their year end stats you will see that the vast majority of the money is coming from Activision and not Blizzard. As others have said here its about Skylanders doing well and also the upcoming launch in China and also CoD.
Additionally everyone would expect a stock jump with year end reports, you only have to look back at the trends of their stocks over the last 4-5 years and can easily see a jump each time the year end reports are issued.
Cant believe I am bothering to reply to a BenBos post as I know any form of intellectual converse is out of the question with his one track close minded Blizzard can do no wrong white knighting crusade.
