I can't honestly say I know where the XQD format is going. So few cameras have adopted the new format, but as bit rates will need to continue to increase to match the continuing rise of megapixels and video resolution, perhaps the format will begin to take hold out of necessity. Either way, for those with cameras like the Nikon D4 or D4S, Lexar just released their fastest XQD cards yet, the XQD 2.0 cards, supporting up to 440 MB/s transfer rates (or in other, less useful, but impressive-sounding terms, speeds up to 2933x). Meanwhile, the CFast cards are even 20 percent faster.
