Some experts are predicting that Ethernet will move into the WAN. What do you think?

I think that it is a great possibility that the Ethernet would move into WAN because the nature of the WAN is that it needs a network that is capable of high capacity and high traffic. The Ethernet has emerged to be a network that is predominantly utilized for high traffic from 2 Mbps up to 1 Gbps. This makes it a great contender for movement into a WAN.
