you forget that the PS3, like every othe product ever made, has a lifecycle. right now it has just entered the growth phase. next year its sales may increase by 50%, the year after that perhaps it will grow by 65% and year on year it will slowly have rising sales and in 5 years maybe it would have reach maturity and begin its descent into decline where it will lose sales year on year for another 4 years perhaps. It will sell over 100 million if sonys 10 year plan works but I think a 7-8 year life is far more likely as the wii will be replaced by then and the 360 will more than likely have a successor and a respective date announced.
