I want to know the answer to the following question:
How many PS3 did Hirai set a public goal to sell by the time the product was nine?
All the background I'm provided with is that "In a July 2008 interview, Hirai stated that his objective is for PlayStation 3 to sell 150 million units by its ninth year, surpassing PlayStation 2's sales of 140 million in its nine years on the market.". Is that enough to answer the question?
