None of the clubs mentioned so far who have announced prices (Blackburn, Norwich, Wigan, Huddersfield) know which division they’re going to be playing in next season.
I’d guess the stadium situation is most likely behind any delay.
I don't see it makes much diiference what league we're in. If we stay where we are season ticket holders get 23 games, but if we go up they get 4 less, so there is already a pro rata increase built in should we get promoted, if the price is the same in both scenarios. I imagine its match day ticket prices which are more variable, dependant on whether we get promoted or not.
