Sony just can't catch a break these days.  According to the AP, only 100,000 units for Japan launch.   400,000 units for holiday in US, and delayed in Europe until March '07.  The blame is being placed on a lack of blue-laser diodes, needed for Blu-Ray drives.  Supply-chains matter.  It's looking more and more like this holiday season belongs to Xbox 360 and Wii.
