I'd rather use firewire than USB 2.0, I don't want to get into a firewire vs usb debate, but I'd rather use the FW
But, if lower end cameras are coming out capable of USB 2.0 transfers, well that would be a step up from the usb 1.1 available now.
I was planning on buying one around christmas time, but if I hear of some USB 2 cameras coming out next year, I don't have a problem with waiting.
