Um, infamous' first paragraph is correct. But those facts are not somehow damaging only to Sony fans who want to see more PS3 sales. Microsoft fans who like to tout 360's greater sales must realize that there are market forces at work here beyond any fault of Sony. So: Sony fans, the current economic environment makes it hard for PS3 to sell more and easy for the 360 to sell.

As for how Sony, financially, could manage to lower prices, it comes down to whether they think they could recoup costs through game sales...but if their finances aren't that strong, they may not have the ability to wait around for their install base to generate the game sales. Personally, it's hard for me to accept that they couldn't wait it out and reap rewards long-term after dropping prices and getting more PS3's out there, but thus far Sony are waiting. I think some time next year they'll definitely drop prices; dropping production costs will happen even though the currency market and consumer spending power is bad for them right now.
