Sony began manufacturing high-definition Blu-ray discs at its plant in Terre Haute, IN Tuesday. In a statement, Dieter Daum, president of Sony Disc and Digital Solutions, said, "Blu-ray is going to revolutionize the way consumers enjoy and interact with high-definition entertainment content." The company said that it expects the first releases on Blu-ray discs to hit the shelves next month. That's also when Sony expects to begin shipping its Blu-ray-equipped VAIO AR Premium laptop computer at an eye-raising price of $3,499. It has said that it expects to ship stand-alone Blu-ray players in July. Samsung said last week that it will be the first to sell a Blu-ray player when it begins shipments on June 25.
