I also read somewhere that it costed Nintendo like $100 to make the 3DS when it was launched at $250(profitting) but when they dropped the retail price to $170 they were losing money each sale so R&D(manufacturing and getting it into retailers hands) has to cost anywhere from $70 to $140
so lets just take $100(for R&D) and add that to how much it costs Sony to assemble the PS4
This is why i always said that i wanted Sony to make a $500 console(including R&D) and sell it at $400(losing $100 each PS4 sale) at launch
The profits lines will be met much quicker than when PS3 was supposed to hit the profit line. PS4 will be cheap and will BOOM in all regions at that $399 price point from jump so they wont have worry about every developer and all the fans crying for a $100 price drop(basically widening the the time it would take to reach profit lines and makeing them take losses for a much longer time than originally expected)
it will be cheap enough so the kids can get PS4s and the games will sell from jump which will offset a lot of those losses
