To be sure, a lag is normal -- it may be until the end of the year before such systems can even be assimilated into core networks. And at first, any benefits are most likely to be seen by the carriers themselves, in reduced operating expenses for deploying and managing their services.
But the real proof of the new router's worthiness will come when the service providers who deploy it start using it to deliver more services, flexibly deployed, at lower costs.

Just as assuredly, however, they will be silent as to when they'll be able to serve up a tasty, low-cost sandwich of services using the new gear.
