Olympus Japan has today announced another step in capacity for the relatively new xD Picture Card flash storage format, according to the press release they expect the 512 MB xD Picture Card (M-XD512P) to go on sale in Japan this June (next month). This new, higher capacity card, is already compatible with several recently released Olympus digital cameras; C-5050 Zoom, C-50 Zoom, C-730 Ultra Zoom, C-740 Ultra Zoom, C-750 Ultra Zoom, Stylus 400 (mju 400) Digital, Stylus 300 (mju 300) Digital. Although not confirmed in the Japanese release we assume this new card would be compatible with the US models D-560 Zoom and D-390.
