Drat. Read the IGN story late...
Wouldn't it be CHEAPER to produce the things sans-memory, though? Adding an eprom or flash memory to each card seems like it might get expensive in the long run (albiet not by much, perhaps), compared to making a stand alone memory card...
I was under the impression that the matrix memory itself could be written to by a consumer device, but only once... wouldn't that be a problem for memory storage? If so, and you have to add something to the card to allow saving, why not just go with a stand alone memory card?
