I agree that it's worth considering, I think it has extended range as 
well. Competing very firmly with
  GiGe!

Yes, I found that same thing.  Seems odd that Cypress wouldn't be one of 
the front-runners for
  USB-3.0.

I will point out that one of the enticing things about 1GiGe is that you 
can run it over extended distances.
   Which for me is very interesting, since you could put a receiver at 
each antenna (think Alan Telescope Array),
  and haul signals back via 1GiGe.  With USB-2.0, you can't do that 
without a funky device like the ICRON Ranger
  series (which inside, just re-packages USB-2.0 over 1GiGe, as far as 
I know).
