I think that if they do the pricing structure well in the new arena it will bring in a much younger crowd. The fans between the ages of 17-24, if they can grab tickets for $10-$15. With the amount of colleges in North Jersey, as well as the amount of high schools within reach of NJ Transit, it will be huge.
When you sit in the cheap seats at a baseball game, there are entire sections of kids that bought the $10 tickets. The Devils could capitalize on this.
I will go to way more games in Newark because I live within walking distance of an NJ Transit station!
