Being that people had the option to buy a $500 PS3 and it was not popular enough to maintain the model I don't think a $100 price cut will have much of an impact on sales. I would anticipate a 25,000 unit boost the first week, followed by a 15,000 boost the second week, and then the PS3 will probably only gain (on average) 5,000 units per week over what they were selling.
I could be wrong but I think the big psychological problem that the PS3 faces is that no matter what you buy it will cost more than $500 by the time you leave the store; at $400 you could buy a system and a game (or extra controller) without crossing this barrier.
