Despite the price hike, I think next season's attendances will hold up (if partly through some of the away followings).
Although next season we've got MK Dons with a poor traditional away following, Bolton, Charlton, Oxford, Northampton, Bristol Rovers plus possibly Pompey etc should bring decent followings. When you remove the likes of Crewe, Colchester, Burton, Blackpool & Doncaster etc , it should nudge up the numbers?
