Blue-violet laser semiconductors installed in other Sony products were produced in a single reactor while for PS3 they had to use multiple reactors at the same time to process millions for the shipment target. As for buying laser semiconductors from other companies, it was not possible since others still can't handle mass production of these chips. The mass production of PS3 was delayed from early Septmeber to late September.
The US market is prioritized as Thanksgiving is in November. From late September, mass-produced PS3 will be shipped by boats to the US and the last batches will be by air. Since PS3 will be manufactured in Japan and China they can secure the assignment for Japan later than for the US.
As for Europe, PS3 shipped by boats in late January will reach there in early March. However, for the launch day, 1 million PS3 are secured for EU. They plan to ship 1.5 million PS3 to EU in March.
The initial target, 6 million PS3 till March 2007, is unchanged. Their internal target was 7.5 million and they plan to increase the output per month to 1.2 million.
Other parts are apparently in good yield. Cell has almost too good yield and they have 3 million of them. RSX, the 90nm southbridge chip, the RF controller chip for Blu-ray called "Savanna" are in good yield too.
