I've been looking to get a new, bigger SD card for concerts and such (Think 16GB, most of the time shooting in burst), and found out about UHS-i/ii cards, how it was a new technology more or less around 2009/2010, how most devices should support them and how my camera should take advantage of it.

The thing is I haven't found anything close to "official" confirming this: From people on DPReview talking about the camera supporting and taking advantage of, to people saying the complete opposite, getting to the point of someone saying the camera would not take advantage of a card faster than a class 6.

Can someone enlighten me on this? Where could I find some information? Thanks!
