You think cable companies have that much unused downstream capacity lying around ready to be used pretty much straight away?
Finding another 64MHz for this year's upgrades was a non-trivial task. Some areas are going to need, and will receive, plant upgrade to go further. Part of this upgrade is 85MHz mid-range upstream with a relatively easy upgrade to full DOCSIS 3.1 range via diplexer swap.

Only the current generation of 8 down 4 up D3 CPEs. Wasn't the VMNG300 theoretically 4 down 4 up, and DOCSIS 2 and before were all 1 down 1 up anyway.

If dealing with VM:
I mentioned specifically
practical ratio and chose my words carefully on that one. EuroDOCSIS 1/1.1 you were dealing with 50Mb downstream, 10.24Mb upstream channels, usually at a ratio of 1:4 or 1:3 making offering anything like symmetry extremely unwise as channels degraded at c.70% utilisation and upstream usage was way more constant than downstream.
EuroDOCSIS 2.0 is a different animal but still maximum upstream bandwidth 27Mb with same restrictions on channel degradation hence perhaps 20Mb usable at most. The highest service tier I've seen on DOCSIS 2 was 10Mb.
Statistical contention has left more options and this effect on 3.1 will be even more pronounced.

Didn't we establish VM were going to start deploying D3.1 early next year?

Did we? Liberty Global doesn't mean VM by default. This tech is more likely to be deployed where a Liberty Global company is in competition with FTTP or where a hardware refresh is due.
The plans for the next couple of years at least are focused around DOCSIS 3.0. Subject to change of course.
VM are deploying new kit, some of which is DOCSIS 3.1 ready, however 3.0 supplies what is needed for a while. It's not like Openreach are pushing hard with their 80Mb/20Mb FTTC product - VM will be offering the same or better than anything Openreach offer in consumer grade services anywhere in their footprint by the end of the year.

Was it?
