A tiny but significant factoid in Sony's earnings report from the WSJ: "Sony loses about six cents for every dollar of PS3 hardware sales."
Educated guesser of component prices iSuppli had deduced that Sony was finally eking out a little bit of profit on every PS3 Slim they sold, thanks to lower costs, but apparently, not the case! They're hoping to cut production costs by 15 percent by March 2011. Hey, at least PS3 sales were up 44 percent. On the other hand, no one's buying the PSP Go. Sony cut their sales estimates by third for the year.
