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.
