That's the problem, you say they "will be", but they are not available yet. Even when they are, they are still going to be class 10 at first as far as write speed. The fastest max speed write speed so far I've seen is 30mb/sec (not guaranteed, they only guarantee class 10, so 10mb/sec, any more is a bonus)
Panasonic's press release. Berlin, Germany (September 1, 2010)
"With the higher reading speed of up to 60MB/s, the 8GB and 16GB Memory Cards can transfer data to a PC more than two times faster than Panasonic's current Memory Cards.3 These also offer stable writing performance with Class 10 speed specification, ensuring highly-reliable 3D and full HD video recording."
There is a reason why pro DSLR's come with CF cards, because they need them. Pro level DSLR's will continue to come out with CF cards because as the megapixels go up so does the need for faster cards, and many of them need 2 slots to help keep up. CF isn't resting on it's laurels either. Faster cards continue to be released in that format.
Originally posted by RonHendriks1966 When it comes to cost, the SD really isn't cheaper. Of course a card three times as fast will cost more, but compared to a CF with the same write speed and the price difference is negated.
SanDisk 16GB, Extreme 30mb/sec $109
SDSDX3016GA31 SanDisk 16GB, Extreme Secure Digital High Capacity (SDHC) Memory Card, Class 10
SanDisk 16GB Ultra 30mb/sec $65
SDCFH016GA11 SanDisk 16GB Ultra Compact Flash Memory Card with 30MB/SEC Speed
The CF card is cheaper by a large margin. So if cost is important one can just buy the slower card and even save some money. Where as if someone needs the buffer to clear quickly, with a SD card they are stuck with long buffer wait times. I for one would like to have the choice.
Like I said, SD is fine for an entry level soccer mom camera, but not for a flagship "semi pro" camera.
