QuoteEngineering one-upsmanship aside, combo DVD players will likely be costly, at least initially. Standard Blu-ray players cost $600 or more, and HD DVD players go for $400 or more. The lasers used in Blu-ray players also remain in tight supply. That limitation played a role in Sony's PlayStation 3 shortage as the game consoles--which contain a Blu-ray player--went on sale late last year. A combo player would have duplicative or more specialized parts and thus cost even more. Another factor adding cost is royalties. Manufacturers that build combo players have to pay fees to both the Blu-ray and HD DVD organizations. Although LG has said it will ship its combo player in the first quarter, it won't reveal the price until Sunday, a spokesman said.
