Sony has announced a new S Series XQD card that will give photographers read and write speeds of 168MB/s.  The existing H Series XQD card is rated at 125MB/s. Of course, the only camera to currently utilize the new XQD format is the Nikon D4.

With the new S Series cards, the Nikon D4 will be able to capture a burst of 108 RAW images at 10 fps.  As Sony notes, "this lets photographers document the men’s 100m sprint final from start to finish in a single, sustained burst of RAW images."

The 64GB S Series XQD card will ship later this month.  And, a 32GB model will be available in the September/October time frame.
