If iOS games alone put food on their tables, they might not really care.
To be completely honest though, they make enough money working for other developers, I would think. That seems to be the thing to do right now. I mean, they worked on Star Wars: Kinect (granted, that game was a terrible idea, but still), and now they are working on Saints Row 4. Contract work for things like that aren't cheap.
Edit: Forgot to mention: That would mean that iOS games would go almost entirely into the company fund, to save up some money for something big.
