Do you get anything extra if you pre-order professor Layton and the last specter?

I want to know if you get anything extra if you pre order professor Layton and the last specter in the united states|||I don't think so. No one has said anything about it in the IGN or Gamespot forums, and it's not in Game Informer. Either that, or everyone's just trying make sure that you and me don't find out. Haha.
