Whether you want to ignore the minimum price of entry or not, the typical, expected price of a console was ~$400 and the rival's price was $400. PS3 wasn't $400 until a year after release, when it's sales picked up and stayed pretty constant, no?
It's not a "want to". It was an irrelevant SKU and should not be considered. Sony didn't want to sell it and consumers didn't want to buy it.
FWIW, I don't completely disagree with what you're saying about the PS3. I'm just not's sure it's correct that the PS3's turnaround was driven entirely by the price cut. There was more to it. And I don't agree completely with how you are evaluating sales for the One. It did sell better after it got a price cut. It didn't see as dramatic of a sales increase as the PS3 because the PS3 started from a worse place.
