Not likely.  The Internet is not compressed, so they'd have to compress 
and then uncompress all that data.  One reason they may want DOCSIS 3 
modems is IPv6 management.  While DOCSIS 2 modems can carry IPv6, they 
generally have IPv4 only management.  Comcast, in the U.S. is switching 
it's entire network to IPv6, as they can't manage it with IPv4, without 
segmenting the network, as there aren't enough RFC 1918 IPv4 addresses 
to do otherwise.  They're also using 4in6 tunnels and large scale NAT to 
provide IPv4 service to their customers.
