Actually, not really. GE and 10GE are getting real popular for access, 
in particular, PON-based access networks. There could be tons of GE/10GE 
at aggregation points, but only a single OC3/OC12 toward the core.

The assumption has been that video traffic can be handled locally within 
aggregation networks, (R/F overlay through optical links directly, or 
satellite video download etc...)

What may happened is that large user traffic bursts jam into the narrow 
OC-n links toward the core. This is where proper traffic policing 
becomes useful.
