As expected, Samsung has become the latest member of the Blu-ray camp to announce a delay in shipping high-definition Blu-ray players. The Korean company said that it had postponed its launch until June 25 in order to "complete compatibility testing with several Blu-ray test discs." Sony, which was the lead Blu-ray developer, announced last month that it was delaying shipment of its PlayStation 3 devices until November because "copy protection technology for the Blu-ray Disc has not been finalized." The announcement spiked speculation that other Blu-ray players might similarly be delayed. Meanwhile Toshiba began rolling out players with the rival (and incompatible) HD DVD format on March 31 and said it plans to introduce them in the U.S. this month.
