Not really much to go on yet. If you look at the current codex, a 10 sister squad (sister superior and 9 battle sisters) is 110 points. Upgrading the sister superior to a veteran (and who doesn't?) makes the unit 124 points. So is the sister superior automatically a veteran now? That would be a 1 point increase on cost for a basic squad. Then there is the matter of the cost of transport which has been about 20 points over cost. Did it get fixed?
I guess I will find out soon.
