If you think TW has been looking ahead, you are deluding yourself. It has been obvious what direction the bandwidth usage has been headed for years. Yet, TW still has a ton of systems still running D1.1 and D2. If they had really been looking forward, a significant amount of their footprint would be D3 today.
That's a little optimistic -- DOCSIS 3 early-use hardware didn't start manifesting itself until Q2/Q3 of 2008, with final full D3 certified gear arriving in Q4.
Comcast appears to be leading the way in DOCSIS3 deployments, and they aren't even close to 50% deployed yet.
