Gamespot has a new article out that puts the cost of manufacture of the PS3 at $300 more than the 360. Pretty much indicates a sticker price of $300 more (console losses tend to be a constant $100-150 per unit). If they mark it down to be price competitive Sony could very well be putting the company on the line. They would need the Blu-ray to completely drive HD-DVD from the movie market sooner rather than later. They can not afford to have Blu-ray be Beta in this battle (as in the Beta vs VHS battle....superior technology but more expensive and not adopted). Then again they be willing to risk it as Sony electronic is in a downward spiral to begin with.
