As said many times the 50meg will be a new tier using a different system which is soley for the 50mb, so the 2/10/20 meg tiers will stay on the old system so it should give better speeds across the board although ive always got the speeds i should on 20m so i got no problem, this from cable forums on about it.
It's running on a different DOCSIS 3 system compared to the old DOCSIS1/2 and will be multistreamed. Also a lot of the 20Mb brigade will either go up to 50Mb or down to 10Mb (when the 4Mb upgrade finally gets completed) so you should have a more flattening of the usage on the old tiers which will mean on average people getting closer to thier max
According the the info on DS the new platform will be used for 50 AND 20 meg service.
