This time, the fight will be over
DVD Primacy. The loser last time (show of hands, who actually owned a Sony BetaMax?) is trying to position itself to be the winner this time ... with Blue-Ray DVDs. The competing format is HD-DVD, from Toshiba.
Sony is trying to put a lock on the market by putting their Blue-Ray into PlayStation 3 units, and there is already an agreement on the table with Dell to put Blue-Ray Drives into their machines.
Oh, and there's a reassuring statement at the end that both HD-DVD and Blue-Ray will be backward compatible to currently available DVDs.
