PlayStation3 Europe release postponement

It does not succeed in a mass production of a blue laser diode of a basic part of next-generation DVD blue-ray disc carrying as expected that European release of PlayStation 3 is postponed.
Sony succeeded in trial manufacture, but there are many defective articles which impurities stick to the surface, and is not usable when mass-produce it, and appear, and cannot keep the quality that it is necessary; is in a situation.
Therefore, like an example of a collection of data mining practice, there will be necessity to find a process of defective article outbreak in a factory in by data mining.
Technique is regarded as "decision tree" in that case.

European release postponement is the second since I review it in November from this spring.
Japan releases U.S.A. on schedule with November 17 on November 11, but it is a prospect to remain in a half planned around 500,000.
It seems to be generated by excessive demand so that a petit bubble of PlayStation 3 is natural.
Was until the end of the year, and regarded 4,000,000 of them as injection universally; is to ship it, and will seem to revise a plan downward to a little over 2,000,000.
An investment muscle reacted to it, and Sony stock cut in on 5,000 yen.
The future anchor product which was equipped with a function of the blue-ray disc which PlayStation 3 was not a simple game console, and Sony promoted.
It is said that a customer may seem to stream down XBOX360 of Microsoft of a competitor, Nintendo Wii, but thinks that nobody knows so it because it is the killer contents order that it does not think of, but.
Is obstinate for some reason; write it, and person is still a hard viewpoint.
I think that killer contents spend metal gear solid 4 of natural Konami Kojima production.
