Compared to PS2 's brilliance will Sony admit that PS3 is a kind of failure?

So far, Sony has sold 35.6 million sets of PS3, and in number two other major host Wii and 360. At the beginning prices were the main reason for restricting PS3 sales, and PS3 sold 599 dollars at the 2006-year sale. Now the price of PS3 has been below 299 U.S. dollars, 09 PS3 sales also increased by 2.78 million, market share accounted for one-third of the world. In the case of Sony's reduced PS3 costs, PS3 sales have been growing. But these are bleak compared with the original PS2 brilliance. PS3 's sales have lagged behind the Wii and 360 because of the initial market strategy of Sony.　　Has lost its edge in price. Sony Development PS move is to take back from the Wii in the hands of the PS2 users.　　PS2 has sold 140 million units worldwide, but PS3 only 35.6 million, PS2 in the last 4 years still sell 620,000 units, PS3 estimated to sell only 41 million units. In the face of PS2 's brilliance, does Sony think PS3 is a failure, if this year's PS3 sales not more than 12.5 million units, maybe we will have PS4 next year. (Edit Zhang Xing)
