It looks like Canon and Panasonic (could be more but not confirmed atm) announced some compact digicams that can use SDXC cards in addition to SDHC at CES currently held in Las Vegas.
As my interests are more about the new card and its usage as computer storage, I chose to upload some of my questions here.
The announcement from Panasonic USA about the card is here.
The prices are prohibitively expensive when compared to SDHC, so I would not buy one until I think the prices become reasonable but I do have interests. (US$ 599.95 for 64GB and US$449.95 for 48GB, available in US from Feb.)
questions:
1) Can SDXC cards be used on older cameras (both compact digicams and dSLR's) that use SDHC by updating the firmware? If affirmative, will the camera manufacturers do it? - the file format system looks like different from SDHC but ,as I understand it, it is a firmware issue? (this is purely a question and not saying it is.)
2) when will new dSLR models that can use SDXC (in addition to SDHC) be announced? Most likely at PSA in Feb? SDXC looks like more suitable/needed for HD video recording.
3) The data transfer speed of the two SDXC cards are said to be up to 22MB/sec. (speed class 10) . When SDXC's idea was announced a year ago, the announcement said the max speed would be 104MB/sec and possible to improve it to 300MB/sec. iirc.
So the announced two cards look to me rather slow in view of their theoretical potentiality. I guess this is faster than SDHC but still slower than CF cards. In other words, not fast enough to replace CF cards still widely used on dSLR's?
My understanding is that as SDHC is slower than CF (around 37MB/sec.) , so manufacturers continuously use CF cards for some/many dSLR's to get more fps. Once the speed of SDXC exceeds that of CF, then CF cards will just disappear from new models... ?
4) when will 2TB SDXC will become available? will it make computer (also camera ) size smaller? or two slots of SDXC cards become a standard feature for, say, pro dSLR models?
When prices are equal between 2TB SDXC and 2TB Hard Disk Drives, I will surely buy SDXC.
Hopefully I can find answers to some of the above when PSA is held in Feb.
and can have rough idea about the road map.

P.S. I also learned that Sony announced compact digicams that can use SDHC (not SDXC) in addtion to their memory stick. So time is surely changing. They are getting more flexible in their attmeps to recover market shares in compact digicams?

But anyway we do need more entrants to reduce the prices...when will samsung announce theirs?
