I imagine the first season in the new stadium will be comparatively cheap compared to other new-build stadium owners while Knighthead get a feel for what they can get away with, but people need to remember that these people are shrewd, ruthless businesspeople in charge and they will absolutely charge as much as they possibly can. Personally I am surprised they didn't charge more for season tickets this season as they definitely could have gotten away with it, but maybe they're still in their "build up good will" phase with us fans.
I think as soon as the new stadium + Prem rolls around, they will really start to drive the prices up. I wouldn't be surprised to see £50+ matchday ticket prices in the Prem while at St Andrews. Got to remember there are 4 fewer Premier League home games as well so they will bump the charge up to cover for that as well as the increased popularity of the club being in the Prem.
