I just think people would have rather seen things like improved scouting, trade logic, draft day, player growth, etc. I think a lot of people here (me included) are buying this game to simply play hockey, so we don't really care about concession prices too much.
I think the owner-type things they have added this year would have been a cool addition after they nailed down some of the basics like scouting a little more. Even still, they should give you an option to turn this stuff on "auto" so if you don't care about popcorn prices you don't have to worry about it.
For me, I'd take improved hockey-related items in Franchise Mode any day before I got the ability to change concession prices.
