I want to know the answer to the following question:
What other Sony gaming console was Hirai setting his sales goal to beat?
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?
Answer: yes
