Re: 20 Meg to 50 Meg upgrade.
I personally doubt Virgin Media will increase the upload speed by a huge amount due to the current Docsis 3 approved specification. The current spec only increases the download speed and NOT the upload; the total available upload capacity will still be the same and the current implementation.
The final spec will however allow for the upload channels to be bonded the same as the download, until then no hardware manufacturers are making hardware capable of bonding the upstream.
Hopefully it will just be a case of a software upgrade!
