Sony made the "10 year" system remark for many reasons.
1. They thought they would dominate the market just like or even more then the PS2 did so that when the PS4 comes out in 2012 the then cheap PS3 could still sell for two, three or even four more years.
2. They wanted to people to feel that the PS3 was a long term investment, like a expencive TV or Hi-Fi system.
3. If you are not going to have a great start it´s always good to say that you are running a marathon not a sprint.
4. Round numbers are cool, face it, how long did the Roman Empire last ??? 1000 years. How lond did Hitler say the Third Reich would last ??? 1000 year. I´m not in any way comparing Sony to Hitler, I´m just saying propaganda needs catchy phrases like that.
