The 2960s seem to be in the background for the management side of the network, doing ikvm and the like, therefore don't need 10 gigabits. Also, the copper in the core routers seems to be more a case of the routers still having enough bandwidth for the site, just needing more bandwidth, thus more ports aggregated. 10gig ethernet's a good amount cheaper than 10 gigs of fiber and works just as well for the short run they're doing..
