Resegmentation is irrelevant to the analogue switch off. Analogue switch off frees channels on all segments, however there is already the existing ability to push more than one downstream down a single segment and I'd hope that the network isn't so rammo that there are no 8MHz slots at all free.
Resegmentation itself isn't a magic bullet as it can be massively expensive especially when having to split nodes, pull fibre and build new cabinets. There are only so many nodes that are combined to each card and once you're down to a node a card it starts getting really expensive.
As I said, foreseeable future
There's also the cost-benefit to consider, how much are you going to break a network down. It still also is unavoidable that 4 10Mbit users can saturate their area, all you can do is minimise that possibility by breaking down to as small an area on each card as possible.
