I hope they do use the blue laser as at the moment they are very expensive but if someone like sony starts to mass produce them that will bring the price down far enough that they will start making consumer level DVD burners using this shorter wave length laser enabling us to store huge amounts on DVDs for less.
Last I heard a blue laser burner would retail at an estimated 2 to 4 grand US.
Please Sony - mass produce this laser - this technology needs to become affordable for us gadget hungry consumers!!
