As part of its September quarter fiscal results, Activision Blizzard has announced that it has "authorized a stock repurchase program under which the company can repurchase up to $1 billion of the company's common stock." The company's stock price has been in decline since September (and has taken a noticeable hit today, too). While the motivations aren't known, it is likely in part to increase the earnings per share. Don't feel too bad for A.B., though. After all, Wrath of the Lich King is just around the corner.
