I don't think we're going to get a sudden rush of people coming back unless its right at the end of the season and we're still in with a shout. At best it will be a gradual increase.
I'm convinced those match packages are having a positive early season affect on attendances. I bought one - have been to the first 3 home games and am rekindling the 'habit' of regularly going to the game rather than the handful of home and away games that had been the norm for the past few seasons (much as I love the City). Just trying to keep my wife sweet and hoping my regular disappearances on a Saturday don't trigger the annoyance button !
