That's great that Sony moved that many units during launch. It just shows how much the Playstation brand was strong and still strong to this day.
From a business perspective, when one loses over 200$ per console, one can hardly call that a success. Up until late 2010, Sony was not making any profits and lost over 4.2 billion US$. I call that a failed business transaction.
