Just because it's almost an expected standard doesn't make it better. USB2 is not as fast as firewire nor does it have the features of firewire which is pretty much a SCSI standard implemented in serial form.
The other really good feature/s that comes along with firewire is the fact that firewire does not need a computer host to run, just like SCSI and Firewire can also connect up to 63 independent devices including network structure hubs etc.
You can connect up digital camera to printer setups with no memory usage, no cpu interaction and speeds are now used up to
780 Mbits/sec Mind you I think the standard has potential to go over 3 gig. That's faster than any twisted pair cat5e/6a cable.
The only reason for it not taking off is probably, it Apple. I think they have to pay Apple a small royalty to make hardware or some such thing. It's not much, but it's something.
