After DVD-ROM, BD-ROM

The "Blue-ray Disc Founders" consotium presented the soon to be heir of the DVD-ROM. The BD-ROM, based upon Blue-Ray technology, will hold from 25 to 50 Go data, thus enabling the use of very high resolution films. As for burners, Sony Blue Ray double layer will be up to burn 50 Go (by the end of this year).
Yet a future competitor will challenge it by the same time (2005), the HD-DVD .
A new war is at hand, and shall probably delay our use of those products.
