I'd be very surprised if City looked at this from anything other than a financial perspective. I remember a few years ago seeing matchday income per fan of each of the PL clubs at the time. Chelsea topped it at around £1,600 per fan each season. Arsenal, Spurs, the rags and dippers were all at a similar level. It was measured against the same data from a decade earlier and rises had been between 3% and 90% iirc. We were sat below them having gone from about £350 to over £1,000 in that period at a 180% increase. That's a monumental change, particularly when you consider the historic prices blues would pay to attend games. Yes we're the best in the league and have been dominant but that's such a major change in cost it's not surprising many historic fans have stopped going. It used to be cheap to watch City and the football was shite so it would be about a beer and a sing song.
The club will see a huge gulf in income compared to our rivals. It could work out as a player a season by the time you run it through considering the higher attendances at Spurs, Arsenal and the swamp.
It would be lovely for them to market the NS as per the suggestions by 1894 and in line with what Didsbury Dave has said. That's the ideal method in my opinion. Create a buzz around it, talk of the Maine Road days. Entice the old singers back through attractive pricing - although they'd have to wait their turn. Make the stadium an environment where people are willing to pay more and come because it's bouncing - there is a market there particularly with younger audiences. Seats in the SS from movers can be available for those who are struggling with the costs in the CB and ES. Then you sell those seats to day trippers who will happily pay a fortune to see us. Overall though that's going to fail every single test on the financial system they'll be looking at this expansion through. It will be the only one that meets the "fan satisfaction" criteria, but even then that will not be universal. So why would they do it? Cost of living crisis? Giving back to the loyal fans of old? I'm not sure they give a shit about atmosphere or fan satisfaction too much when there is money to be made. If they lose someone who has been going for 30+ years and replace them with someone who has more cash and spends it, happy days!
A very cynical view this, and I like to believe the club do care about the fans. As JRB has said, let's hope they're reading this thread and that they'll listen to feedback once proposals are shared.
From what others have posted and what I've bee told in general, the club do want to improve the atmosphere in the ground. How they go about that by redesigning and expanding the North stand will be fascinating to see.
