A final spec has been promised for over a year now, but the PCMCIA folks
have just now finally settled on the long-awaited ExpressCard 2.0 standard
which, among other things, incorporates the new SuperSpeed USB spec to allow for
faster transfer rates. In real world use, that should translate to transfer
rates up to 5Gbps, or roughly 10 times faster than the previous ExpressCard 1.2
standard. Otherwise, you can naturally expect full backwards compatibility with
existing ExpressCards and, as PCMCIA hopes, even more products using the format
in the future now that it has all that extra bandwidth, although it seems Apple
didn't get that memo.
