Well, the hope is that in some future release those and maybe user-defined game events will become available. I've been in a number of forums frequented by EA project people who say that there's a huge wish list of stadium-specific features that they want to include in future games, and not just limited to music (pregame band marches, halftime shows, etc.)
Well I'm setting the stadium sounds now, and they're exactly the same ones they had last year. I have to say this is pretty disappointing. I mean, they couldn't even give us a pregame or postgame option?
