The coax part of the network isn't the reason for our current problems. That can transport whatever carriers are put on it. If they are putting in a parallel and fat system between the core network and the nodes - then it's a separate system in the areas where the current issues reside. So it depends on the definition of "upgrade". If it's "add a couple more links to the existing groups" then you're right. If it's "run in a separate set of really fat, modern pipes" then I'm right. Time will tell! :-)
