Looks to me like a move to keep this format the most expensive on the market

We can thank NIKON for bringing the XQD storage card to life in their D4 Camera. Of course it was a chance, but someone had to take it. Within a few years it will be as much a part of photography as any other COMPACT FLASH or SDHC storage card, but a lot faster with much more storage ability. ... Joe Prete
