If they was serious about providing fast speeds you'd be seeing at least 5mbit upload.

Whilst the DoCSIS 3.0 Modems only have the ability to be registered on a single upstream and that upstream can only be 3.2Mhz QAM16 (10Mb/s) then it is very unlikely that 5Mb/s Upstream would be viable (2 simultaneous users bust the upstream). Higher Upstream may come when upstream channel bonding is available (2009/2010).
The other option is to spend shed loads of money to bring the return path up to a higher quality to support QAM32 or QAM64.

I am interested how some of you feel it possible for VM to offer greater upload speeds on a network that only has 30Mhz return path spectrum in which to work?
To me that breaks down as only having between around 18Mhz and 30Mhz to use, so 4 upstream channels.. 3 x 3.2MHz QAM16 and 1 x 1.6Mhz QPSK shared across around 400 customers
