gorgepir, I think the point that you're missing is that you don't have data available to see what sales would have been had the price not dropped.
I'll take your PS2 America numbers as an example. So at $199, the PS2 sold 900+ a month, and at $179 it sold roughly 600 a month. This does not mean that the price cut didn't help sales. There are tons of other factors left out of this analysis, such as major game releases, what the competition is doing, market saturation, etc. If the price had stayed at $199, sales would probably have been lower than 600 a month during the same time period.
