Vectoring is designed to help negate the crosstalk, and BT is planning it, but not for a couple of years.
There is a good reason the speeds for distance versus connection speed on http://www.thinkbroadband.com/guide/fibre-broadband.... are so pessimistic, this takes into account worst case cross talk on VDSL2
There could be a problem with rolling out Vectoring. The next stage will be going up to Profile30 and that will require, potentially, almost twice the processor power for the software modem on each line. Add in Vectoring which needs to monitor cross talk and then generate an appropriate cancellation signal across the whole band - that will require further processor capability.
Are the current lines cards capable of the increase in CPU load? Potentially not.
