I don't think you have to worry about it getting anything higher than a Teen rating.... Remember this is AT, not Mortal Kombat. If the previous games have gotten the same, what makes you think this won't? I know the ESRB can make some really weird decisions at times(like giving Persona 3 an M rating?), but I think they realize that people in the this category are probably 14-15 year olds who know what they're getting themselves into.
The Mature tag is the tip of the ice berg for North America(barring AO), so its only really given out if there's some really offensive material present in a game. Trust me, this game definitely won't cross that line.
