I think the key to increasing student attendance will get ironed out eventually.
The apathy aspect of it all is going to weed out those who simply have a fleeting interest in going to games. The stadium won't be brand new next year, students now know they can't scalp their tickets as easily as in the dome, they have experienced the cold weather, this will weed out the students who just don't care that much. 
The incoming freshmen should get a chunk of tickets next year, this years freshmen will hopefully continue to show up and make a day of it all, apathetic juniors and seniors will graduate, hopefully dedicated new alumni will buy regular season tickets. 
Eventually it will all work itself out, unfortunately everyone wants perfection right now, same with the team, same with the stadium.
