On 12 of February SanDisk announced the new memory cards in pro line - SanDisk Extreme PRO SDHC™/SDXC™ UHS-II card.
Cards are available to preorder from SanDisk or B&H
My first reaction was - "I want it!", but after checking compatibility with my camera realized that it would be a waste of money for me. At the moment the only camera that supports UHS-II standard is Fuji X-T1.
