I agree.  I also don't buy into the suggestion that some later *ist-Ds may
be USB2.  For one thing, most of the people reporting good transfer speeds
are early adopters, and were testing some of the earliest *ist-Ds manufactured.
More importantly, though, you don't change the design of electronic equipment
during a manufacturing run.  If the circuit board was designed and tested
using one particular I/O chipset then that chipset will be used in all of
the cameras.  Switching to a different chipset (no matter how compatible it
is claimed to be) would necessitate a whole new validation and testing cycle.
And if the I/O is a silicon subroutine from the chip fabricator, then you
don't even have the option of changing it without a whole new chp design.
