Team Xbox, a website not dedicated to the PS3 in the least, has posted some details that were scraped from the latest issue of PSM, the unofficial Playstation Magazine. In regards toward what the price for the system will be, PSM states "According to Sony, the price of the system 'will not retail for under' about $425 Japanese yen. Since game consoles are typically a little cheaper here in the U.S. than in Japan, it's reasonable for us to expect to see a price tag of $399."
