I dont think anyone expects any 'new' season tickets to be bought.
And the evidence of very low potg supports this.
I think people only expect potential veteran ST holders to renew (assuming by your post, that you are one).
So. Veterans seats won't get snapped up?
Another veteran "had this seat for years" will only renew to their seat.
No one new is going to get a season ticket.
There's no vultures circling to try and snaffle people's seats.
I think the club and new owners would try to support the veteran ST holders.
I also think if say a change of ownership happened and some 'new STer' was faster to buy a ticket and picked your seat that people would be understanding and if you bought one for the row behind/a few seats along/whatever the person 'in your seat' may well be willing to swap?
Maybe they'd go on to sit behind you and your friends and family for years to come, maybe they'd become a friend....
