Yeah, exactly. 'UK's fastest 160meg broadband' wins over VM 120meg broadband even if VM is far more available.
They also know that it means VM can't advertise fastest broadband without releasing a faster product, which would really, really strain their DOCSIS network at the moment.
Yes - VM are just now releasing 2 upstream channel bonding for their 120Mb/12Mb product. Going to 200Mb and 20Mb upstream would be a new tier given how recently they'll have done free upgrades.
It's not impossible though, just means pushing the network even harder than the 100Mb/10Mb product did as there are more modems on each 2 bonded channel group than there were on each of the channels alone and they lose statistical contention benefits by offering the same 55% of the channel capacity they did running 10Mb upstream on a single 18Mb channel.
With upcoming traffic management changes it might happen, it's a hell of a push though. The highest upstream I've seen on cable is 15Mb, and that was on at least 2 x 27Mb bonded channels and more likely 2 x 27Mb + 1 x 9Mb channels given 15Mb out of 54 - 63Mb available.
EDIT: Disclaimer - I have seen 15Mb upstream on a single upstream channel however this was using non-standard load balancing, forcing different tiers of service onto different channels rather than, as VM and everyone else do, spreading modems across all channels regardless of tier.
