Well, this is certainly a novel idea that I hope studios in the US will adopt.
Disney Japan announced today that it would begin shipping microSD cards chock-full of Disney movie goodness with the DVDs themselves. Panasonic will provide Disney Japan with the pint-sized memory cards when the DVD/microSD combos ship in November for 4935 Yen. Said combos will begin with the Pirates of the Caribbean and National Treasure series.
There seems to be a catch, though. Your mobile (or GPS) will have to stream terrestrial digital broadcasting for the microSD cards to work. How does that work out?
