No information has come out on Madden, yet.
No one knows if Madden will mirror NCAA at this point, pure speculation and conjecture at this point.
If it's true and the enhanced sounds are included in Madden, we knew from E3 (last June) that Madden was receiving FIFA sound technology for 13. They said they didn't have time to implement the sound technology for Madden 12.
That is what they said.
If true, that enhanced sound better include commentary and cleaning that up. That was terrible last year.
