According to Reuters, "Toshiba is expected to suffer losses amounting to tens of billions of yen (hundreds of millions of dollars) to scrap production of HD DVD players and recorders and other steps to exit the business."
That's what happens in a high-risk all-or-nothing format war. Sony must feel pretty good right about now, especially after historic defeats with Betamax, ATRAC, UMD, and more. Blu-ray in PS3 was a risky gamble: it created a price point that many mocked, and generated a good amount of negative publicity for the Japanese electronics giant. However, it was also the Trojan Horse that allowed it to gain such a large percentage of the HD-aware mindset. With this victory, it appears that Sony's plans are finally coming together.
