Comcast still has "wiggle room" in terms of increasing speeds and the like with what they have now yet they aren't in any rush to increase speeds even though it would require very little work.

Going to every town that Comcast services and running the fiber from the nodes to every house would be extremely expensive and time consuming.

Not to mention that in many areas (like mine) all the cables are underground. This would require Comcast to dig up the cables under streets and in peoples' yards in order to replace them. Not only would this require permission of the home owner, but it would be extremely costly. Plus who would re-sow the lawns when they are done?
