I seen a few years back a FTTH development get completed using GPON - everything in the area got "Full Gig Internet". Speedtest while I was onsite showed about 900Mb/s download so pretty darn close (before they fully deployed).
The interesting part was that the development consisted of 4400 active users the last time I heard but the bandwidth to upstream provider was still only a single GigE and was not hitting serious saturation levels most of the time.
I have worked on server room networking, and found that it takes quite a bit of tweaking of the interfaces and the TCP stack to get things up to 80 percent usage of a gigabit link. Both ends. So your side can go like the wind, but your data source may not be able to fill the pipe. So I agree that, for most people, this will be pure marketing hype. As for the 4400 users, that's the classical oversubscription model.
