What is the industry cost structure for game controllers?
	a. e.g., If I buy a controller from say, EB Store for US$40, how much
do the various people make in the food-chain from start to finish?
	b. I know for software games, their margin is around $2 - $5 per title
	c. But margins for gaming controllers are higher right?
	d. Bottom line here is that if I am planning to manufacture a game
controller, what are the various costs and margins for all the U.S.
players that I need to consider in identifying the retail price?
