@Bitmap Frogs:
Who said crisis won't keep on hurting them? But the long and short of my argument is that I believe a cost difference greater than $200 is quite unlikely NOW. I'm not absolutely sure, obviousy, but I find it unlikely. And I perfectly know that in the past, when the cost of both were higher and so were the terms of the subtraction, a cost difference greater than $200 was very likely, OTOH, even not taking into account that in the past BD was still very expensive, making that difference even larger. I didn't use Heaven knows what wacky reasonment to come to my conclusions, I simply thought about what I can buy at retail price and have it sent to my address for $200, and MS and Sony don't pay retail prices for components and shipping. But if you want a more pertinent analogy for that price and the items and market we're talking about, think that Wii can be sold at less than $240 giving anyway a profit to both Nintendo and retailers. Well, what else I can say? These and those in previous msgs are my reasons and arguments to believe a cost difference greater than $200 unlikely, if I'll find better ones (the ideal would be to know bulk prices), I'll post it, otherwise I'm done.
About your answer to liquidninja, well, I agree, Nintendo found the right way to play the game, and looking at those charts, it did also during generations when it wasn't winning as number of consoles sold.
