Panasonic has just announced a 2.0-compliant 4GB model that appears to fall under the class 2 category of the new format's rating system (out of 2, 4, and 6), which refers to the card's minimum transfer speed in MBps. SDHC cards, which are only compatible with FAT32-compliant current-gen readers, promise capacities as high as 32GB, while offering the DRM-friendly security features that content producers love to frustrate us with. Panny's first entrant into the SDHC game will be available worldwide this summer.
