anyway, this reminded me of the double density and high density diskettes during the early 90s. where you could increase the density or storage capacity of your diskettes by punching a hole on the lower right side of the diskette. that was an easy way to increase storage but at the expense of creating a lot of bad sectors in the disk.
Less is more ehh?
Of course I researched more and yes, I did realize that SDXC is just going to be an updated version of SDHC. I'm guessing that we might SEE these cards available next year, but I doubt anything will be compatible with it until 2012, and even then there won't be many appliances taking advantage of it (SDXC will be too close to SDHC in specification by then I am guessing).
Theoretically, there is a lot of room for improvement on the SDHC card (speed wise), although I think the capacity will stick at 32GB (can be raised if firmware is replaced) b/c no product can really take advantage of more than 32GB other than dSLRs. In fact, until we see actual HARD DRIVES 2000+ times bigger than SDHC cards then we will be seeing SDXC available. Hard drives right now can barely even reach 2TB yet and look at the size of those things. How the F*CK can a chip the size of a finger nail be 2TB in the near future?
Done with ramble. Please add cause I am interested. Sadly, I stupidly bought 2 Toshiba class 4 SD cards for the same price I could of gotten a Sandisk 30MB/s card (around $25 after rebate). :-(
