We don't have a waiting list for season tickets, we've not been overwhelmed by applications for any home games, other than when Pep threw his toys out of the pram before Southampton.
We only actually 'sell out' the usual games, Liverpool, United, and the really big CL games. We may have a run on tickets for the final home match but that's about it.
Any extension of the North Stand would be quite pointless in the current climate. The club will be aware of that and should be reluctant to carry out expensive work
I think we could almost certainly expect to see the club invest in very significant improvements all round the stadium if we were to join a Super League.
That's what City and other elite European clubs will still be planning for. It will happen, it's just a matter of time.
