FireWire (even FW 400, never mind 800) craps all over USB 2.0 from a great height. Far from being dead-end, FireWire 3200 does the same to USB 3.0. In addition to being significantly faster, it's also backwards-compatible with the older standard, unlike USB 3.0 you can just plug a new FW 3200 device into an older FW 800 port and get the faster speed.
