The Wall Street Journal has the scoop on an upcoming book from two IBM engineers that spills the beans on one of the most shocking events in the video game industry.

In

"The Race for a New Game Machine," David Shippy and Mickie Phipps tell the story of the development of the Cell for Sony, revealing that the processor that powers the PlayStation 3 helped in the design of another central processor unit: Xenon, the three-core CPU that powers the Xbox 360.

From the WSJ:

When the companies entered into their partnership in 2001, Sony, Toshiba and IBM committed themselves to spending

$400 million over five years to design the Cell, not counting the millions of dollars it would take to build two production facilities for making the chip itself.

IBM provided the bulk of the manpower, with the design team headquartered at its Austin, Texas, offices.

Sony and Toshiba sent teams of engineers to Austin to live and work with their partners in an effort to have the Cell ready for the Playstation 3's target launch, Christmas 2005.

But a funny thing happened along the way: A new

"partner" entered the picture.

In late 2002, Microsoft approached IBM about making the chip for Microsoft's rival game console, the

(as yet unnamed) Xbox 360.

In 2003, IBM's Adam Bennett showed Microsoft specs for the still-in-development Cell core.

Microsoft was interested and contracted with IBM for their own chip, to be built around the core that IBM was still building with Sony.

All three of the original partners had agreed that IBM would eventually sell the Cell to other clients.

But it does not seem to have occurred to Sony that IBM would sell key parts of the Cell before it was complete and to Sony's primary videogame-console competitor.

The result was that Sony's R&D money was spent creating a component for Microsoft to use against it.
