I have an uncomfortable suspicion that perhaps Jim is looking at a different scenario altogether - stay with a low capacity stadium, but put the emphasis very firmly on a "premium matchday experience", i.e. a massive expansion of expensive hospitality packages at varying levels and, given the imbalance between real demand and supply, reduce the number of ordinary matchday tickets and at the same time, impose a huge increase in the cost of the remaining seats.
Sweat the assets, in other words.
OAP supporters with their concessionary prices and ordinary local folks who can only afford a simple matchday ticket - I don't think they play a major role in the future vision of AFCB. Maybe.
