The trend to use GigE over OC12, even in metro-area networks is evident and could be extrapolated. My opinion is that by the time anything > 10GB/s is seeing wide spread implementation (18-24months out, conservatively) the same chipset will support SONET or ethernet and it'll really be an end users preference. Lucent showed the world that OC48 did not need to be a premium chipset. Cisco and others used to charge > $100,000 per card for OC48, at the same time Lucent's set was rumored < $500.00 in quantity (that is a decimal point, not a comma).
