I would have sworn I read about something similar coming out in the future, but I can't seem to find any rerferences to it at the moment.

We've got an expensive sony video camera at work that has both firewire and usb ports. I've never really used the USB port, so I don't know how usefull it really is.

The real question is what you need to do. If you need to capture from analog sources, then USB2.0 will do fine. If you need DV capture over Firewire, it's going to be a challenge.
