Unless DOCSIS3.1 has some big upgrades planned, they're going to have a hard time competing with symmetrical fiber like Verizon.
DOCSIS 3.1 can handle 10Gb down and 1Gb up, and it does it using (I think) about 2/3 of the signal bandwidth of DOCSIS 3.0 at the same rates. So yes, it has some big upgrades planned. But I suspect we will have to have a lot heavier use of SDV and the death of analog channels alongside internet speed increases as we approach 1Gb in the next few years.
