The first cards I bought for my new D7000 were Sandisk extreme pro 16 Gb back in January. Now I want to get a 32 GB card to backup slot 1. Doing a search brings up so much info, its hard to sort it all out, but the best that I can tell, the Sandisk extreme pro cards are currently the fastest. Is this correct?
Um, actually the literature for the D7K makes special note that it is the first DSLR that can actually take advantage of the new UHS interface. I use Extreme Pro's and can tell they are NOTICEABLY faster than my class 10 cards.

Yep, I bought one 16GB, saw how much faster it was than my Class 10s, and ordered a couple more. I shoot RAW to it in slot 1, and JPG to my other cards in slot 2 for client review.
Still not as fast as CompactFlash, but getting better...

I am also seeing a prominent improvement with my cards. Raw in #1, and backup & video on #2.

I have several memory cards and the only mystery in mind is why are the SanDisk cards so much faster that the other brands. All Class 10 cards are not created equal. Yes, other Class 10 cards will work and are able to write HD video and keep up with the camera (definition of Class 10) but the D7000 can empty its full buffer in a fraction of the time using a SanDisk card.
As to compatibility the new UHS-1 cards are backwards compatible down to even my D40. So even if your camera doesn't need all the speed that the card possesses when you pull out the card and pop it into a card reader to transfer to you computer the extra speed will definitely be noticed. But I do notice the extra speed when the buffer is filled and the time to the shot is reduced when using a faster card even in my D40.
So I plan to keep the Transcend in slot 2 and write any video to that location and also set it for oveflow as I typically shoot raw only.
Since I shoot sports, and shoot RAW, that minuscule buffer needs to clear ASAP. And whatever lets me do that fastest is the card I want. It's a real shocker watching how fast the D2H and D2X empty their large buffers compared to this MUCH newer D7000. To be fair, they are writing smaller files, but I have a 25 frame RAW buffer to get cleared.

The architecture of the new SDXC UH1 Cards have an increased speed, these potentially will be engineered for sheer footprint real estate to compete with CF but, CF Cards can transfer up to 600 speed, twice that of pending SDXC cards and as this marketing war continues, the CF size, possibly will maintain an even greater advantage as increased capacity micro circuitry can be crammed into a larger case so to speak. (IMO)
These newer cards are designed for Video, where constant bit-rates, digital signal etc. (if that's the correct term) need to be uninterrupted because of the nature of live recording.
"by increasing storage capacity from more than 32 GB up to 2 TB. Its exFAT file system handles large volumes of data. The specification for increasing bus interface, "UHS-I," with speeds up to 104 MB per second and a road map to 300 MB per second, and UHS Speed Class are available for SDXC cards and host devices. SDXC's extended capacity will provide more portable storage and speed, which are often required to support new features in consumer electronic devices, mobile devices and industrial devices."
"As a characteristic of flash memory, actual transfer speed varies. Variable speeds are difficult to reliably record streaming content such as video because it requires a constant writing speed. Speed Class and UHS Speed Class provide the constant speed necessary for video recording by designating a minimum writing performance so that minimum and constant speed is guaranteed for camcorders, video recorders and other devices with video recording capabilities under the conditional write operation specified in the specification."

I'm still playing catch up, the articles from the SD association were to inform.
Last time I priced the XC's (before the end of the year) they were about the same as a used 35mm prime lens at K & H.
Something like this: "The 64 GB and 48 GB SDXC Memory Cards, along with other Panasonic GOLD line Memory Cards, provide longer lifetime, thanks to the adoption of Panasonic’s newly-developed Super Intelligent Controller, which evolves the current Super Intelligent Controller used in the Silver line Memory Cards. With the new Super Intelligent Controller, flash memories are automatically refreshed with error corrections, thus preventing data damages and providing longer lifetime....The new SDXC Memory Cards include a new technology designed to minimize accidental corruption caused by a power interruption, such as the Memory Card being removed while data is being transferred. Panasonic’s SDXC Memory Card robustness is reliable even under severe temperature condition from -13°F to 185°F**. For more information, please visit www.panasonic.com/CES2010."
