All next gen systems lose money from consoles, which is why there aren't more systems on the market (Only companies that have a lot of money to spare can afford to take the loss, which is why Microsoft, Sony, And Nintendo are the fore-runners).

They actually make most of their money off of the games themselves. It's kinda like McDonalds... you think they would be making the money from your cheeseburger, but it's really all from the drinks.
