i think one thing people seem to forget is that over time bandwidth
demands increase.  already, it'd be better to do 10 gigabit to users
rather than thinking of gigabit as optimistic.  and if you look at it
from that point of view then extra devices can easily get in the way
of speed, and qos etc becomes even less important.

if you're doing connections to multiple end points then the standard is
simple vlan tags.  and a 10 gigabit switch makes more sense than a 10
gigabit router with current cpus/systems.  even gigabit routing is a big
struggle on low end devices and although hardware based forwarding is
starting to trickle down to low end gear, it'd be trivial to DOS a gigabit
router.

10 years ago gigabit was fine, and could keep up with hard-disks.  even now
gigabit can't keep up with hard-disks let alone ssd's, and in 10 years time
it is very likely that gigabit will be seen as slow/old/antiquated.  

if there was a direct fibre connection, it'd just require an upgrade to a more
recent gpon standard, and to get a new switch if using multiple connections or
a new router if using a single connection.  at a cost similar to the cost to go
from 100 megabit to gigabit currently.

already Japan is starting to do 2 gigabit..
