I don't think so, which is why I was confused by his question and Phil's answer as well. I know you can
view your team income from ticket sales, merchandise, etc. but there is no way to change how much you charge and what not. Either Phil was talking about the PS2 version when he responded, or it was a slip and he accidentally revealed new information for Madden 10 that they had not planned to release yet. Here's to hoping it's the latter.
I don't think it's the actual adjustment of food prices that has people craving this feature, it's what the feature represents towards the entire franchise mode. When people think of adjusting ticket prices they think back to Owner Mode of the PS2/Xbox days and food prices is just one of the many things that Owner Mode had that Franchise Mode on current gen does not. So when people talk food prices, it's more about everything that's been missing from the franchise mode for years, whether it be the Tony Bruno show, player roles, adjustable food and ticket prices, etc. That's my take on it anyways.
