Is A77 Compatible with UHS-1 SD cards

In A77 user manual, it only mentioned compatible with SD cards of SDHC and SDXC, now there are much higher speed SD coming out, for example Panasonic have Read 90MB/s and Write 80MB/s cards of UHS-1 cards:

http://www.ebay.com.hk/itm/Panasonic-16GB-SDXC-UHS-I-Memory-Card-RP-SDA16GJ1K-/200656275216?pt=Digital_Camera_Memory_Cards&hash=item2eb80bc710

Today, Scan Disk also announced Extreme Pro UHS-1 (SD 3.0 standard) cards having 95 MB/s for 8GB, 16GB, 32GB & 64GB cards coming.

These UHS-1 cards are expensive at present, Panasonic's 16 GB priced at $ 295 at eBay, so to buy and try could be a wast of money if not compatible.

Have anybody ever used? Should Sony dealers provide an official answer?

This higher write speed may help the limitation of the A77's small internal memory buffer at the high frame rate photo taking.
