Just working for now on a crude assumption (generally based on the DSL experience) that the wholesale pricing might equate to around 1/3 to 1/4 the end retail price, this suggests that symmetrical fiber services of various flavors might be available for EUR36 - 70 per month - a range which looks (at least to an outsider) highly competitive with cable and DSL. Afterall, it needs to be pitched to the consumer at a point on the price/benefit curve to ensure uptake/switching, so I assume this is the sort of pricing we will see. I need to digest all this a bit more before attempting any more informed comment, and it's late, so I'll content myself for now with just pointing to Rudolf and Yves' fine work.
One thing I do know for sure is that UK residents shouldn't hold their breath for similar developments, at least not if they are expecting significant public sector participation. We may be doing well just to keep the lights on.
Lastly, just to complicate things, the ever-impressive Andrew Odlyzko has published an update on web traffic growth, which seeks to moderate somewhat the "exaflood" argument upon which the "fiber imperative" is based. I firmly believe fiber migration is a necessary and noble goal, but I also have a soft spot for contrarians and believe we should not ignore empirical data in preference to preconceptions.
