We have talked at length about Google Fiber here on DF. Comcast is looking to one up Google by rolling out 2 GB Fiber starting in ATL. Comcast has yet to announce the cost but you can bet it will be packaged as part of a TV package, similar to what TDS is currently doing with their fiber service. Question is if Comcast still have enough goodwill in the bank for people to buy into their services vs the competitor (ie Google).
