Comcast are leading the way, and due to the hardware restrictions their product uses 24+ 6MHz DOCSIS 3.0 SC-QAMs and a single 3.1 96 MHz OFDM block downstream.
Upstream it uses the same 4 SC-QAM upstreams as DOCSIS 3.0.
This shouldn't be a shock to anyone, for example VM's DOCSIS 3.0 product used a single DOCSIS 1.1 upstream originally, no upstream bonding for a while.
