Michael Pachter: "The people who were going to buy PS3 and Wii will buy them both still, albeit in a different order. Few people were going to buy Xbox 360 and PS3 both (too expensive and too similar), so there may be a small number of people (200,000?) who buy a 360 instead of a PS3. That number represents lost sales forever. The balance will be ultimately captured by Sony, and the launch delay will be a rounding error in the long run."
