Wow, those are fast.  I have 3 64GB cards (2 are Extreme Pro) and was looking at the 128gig one also (100 MB/s).  Those new ones are theoretically 600MB/s, I wonder if these will work in current-gen cameras?

Beware that these cards are CFast 2.0 cards (http://en.wikipedia.org/wiki/CFast#CFast), which are not backwards compatible to Compact Flash, neither electrically nor physically. CompactFlash is using the 16-bit parallel PATA bus (IDE harddrive bus), while CFast2.0 uses the SATA bus.

In other words, you can only use them in (future) cameras that specifically support CFast2.0.

Yes, i understand this is for future cameras that support it meaning Canon last to the party but if Nikons d800 could use it the buffer probably wouldn't be a prob with 75 mg files. I don't see any spec showing a diff size or shape but images that look like reg cf cards. Where is the info for what you are suggesting? Maybe i read you wrong...

I had my information from the wikipedia page I linked to (http://en.wikipedia.org/wiki/CFast#CFast (http://en.wikipedia.org/wiki/CFast#CFast)), which states

A bit of googling turns up this whitepaper (http://www.hsc-us.com/pdf/Evolution_of_cf_whitepaper.pdf) about CFast, which states that the size is the same, but the interface is different (SATA vs PATA).

Ahh i couldn't lock in to that info. I also realize CFast is the new way to say cfcard version 2.
