porscha, time will tell how the ramp up of FTTH will take place. Clearly, the best we can do is agree to disagree about that subject at this moment. Probably in a year or two from now the picture will be better defined. I tend to view the deployment of FTTH in Japan not so much a function of cost (which are constantly being lowered) but rather a desire to reach ultimate broadband as quickly as possible. One only has to look at the speed at which 3G deployment is taking place there to realize that they want to be first in developing that technology. As for what they are going to be doing with their installed twisted pair/local loop network, my guess is that they will just leave in place because their is no real reason to do anything with it.
As for the impact of Cu@OCx on the deployment of FTTH, I would say that it would definitely slow the deployment of fiberoptics in the local loop. However, without knowing specifics such as costs or time horizons I can't provide a more concrete estimate of its impact.
