Brian, don't you see? The many USB connector and cable manufacturers want produce and make profit. 'Everything' is USB-connected, while it seems as 1394 use to be printers and some video stuff. I think that FireWire 800 is superior to any USB. A small detail, not important, but still to be considered: FireWire is much easier to plugin than USB. I've been crawling on the floor with a lamp, to see why on earth the USB plug doesn't fit.

Vapourware? What's wrong with IEEE-1394, already capable of up to 3200 Mbit/s and able to transmit uncompressed HD video at this speed? USB suffers from loss of speed as soon as you have more than 1 item of hardware connected to a bus, because of serial handshaking with each device. With USB-2, if you have just a keyboard and a mouse connected, you don't have enough speed left to transfer even DV (SD video compressed ~10 x) on the fly. With IEEE-1394, you have none of these problems.
