got the majority of the attention in the PlayStation 3's 2.20 firmware update, it appears Sony has made another important addition by implementing support for cheaper organic dye-based LTH (Low to High) Blu-ray recordable discs. These version 1.2 BD-R's, announced back in September
, are manufactured with a different process that allows plants to upgrade CD and DVD equipment more easily. Existing Blu-ray players can't read the discs, which debuted in Japan last month, without a firmware update. Sony Japan's upgrade web site notes the new support, confirmed by AV Watch; although it went unmentioned in U.S. press materials, we'd assume the upgrade made it over here for any of those looking to burn (slightly) cheaper Blu discs.
