I guess Microsoft hasn't made profit from the Xbox either since they lumped all of their failures into the same division.
Except Sony said in that article that the reason for the loss in 2011 was PS3 price cuts and slowing sales of PS2. Microsoft has made an overall profit on the 360 but it hasn't covered the losses made on Xbox. Nintendo also recently got into similar trouble when they lost a billion dollars due to 3DS price drop and currency issues.
