Most people on the 76/80Mbps tariff already get existing speeds - 70% get 70Mbps or more - they don't need any speed enablers. It's the ones on 38/40Mbps and below it's expected to benefit the most.
Additionally Openreach are rumoured to be implementing profile 30a at the same time as vectoring which will double attainable speeds on short lines - up to e.g. 280Mbps without crosstalk in the real world.
That we can agree on.

As mentioned, new modem/routers will become widespread before the new speeds.
And yes 120 is what I'd expect to be the headline figure for the upgraded current service, with 160/200 being implemented as a new tier. Most people on 76/80 already get 70+ as I've mentioned several times.

I cant reveal too much sadly.
But you have to consider since there is a 40/10 and 40/2 product people who are unable to sync higher than 40 are likely to be on the lower product which in turn stuff's the stats somewhat. If my line only synced at 30mbit eg. why would I pay for the 80mbit package?
Whilst 140 is possible, its not a very high %, certianly not 10%. BT have learnt a little about managing expectations which is one reason we dont have vdsl max (fully rate adaptive no cap) by comparison to your city area example, I started off on 110mbit and am now down to a 71mbit sync, attainable is currently 70 so if I resync again my sync will go down. If someone syncs at 80 on a line that can do 100mbit and as such has a nice high snrm so little chance of been interleaved, they are much less likely to complain than someone with a line that can do the same 100mbit but the max speed is 140mbit on the product, the line is running at just 6db snrm, has too many errors, gets interleaved and the whole situation explodes. I think anything over 100mbit is very unlikely when vectoring is enabled unless its combined with bonding. Personally I think BT wont touch profile 30, gfast will come after vectoring. Also the way the dslam vendors are marketing vectoring to companies like BT is not to roll out lines pushing vdsl2 to the absolute limits but rather allowing rollout of speeds of 100mbit at 400m, isp's using whats capable at 400m as the benchmark.
I respect your opinion and I hope you respect mine, but given the farce adsl2+ is/was with marketed speeds I dont think BT want a repeat and as such will not market speeds based on a 0m attainable distance.

As soon as the went to 17a, my download speed has never risen above 55 meg, which I put down to something in the 350 m to the cabinet. Aluminium, perhaps. I don't know if vectoring will help that situation.

When you get your unlocked modem seph you can check the quiet line noise level, thats an indicator of crosstalk levels on the line.
