Re: 200Mbit coming soon? (According to a survey)

That's not accurate, I'm afraid. You've reasoned yourself into a cul-de-sac.

At the current symbol rate and packing density (256QAM), each downstream channel has 55 meg/sec to share across all DOCSIS 3 users (i.e. all tiers). There is no 50% rule.

Incidentally a 4 channel modem is not constrained to 100 meg - but it's VM's policy not to let people on 120 or 152 have that old modem.
