Under the laws of Nintendo's informational embargo, that will not be lifted until 12:00 AM this Saturday, revealing any information about the contents of the game (even the game manual) is in violation of copyright laws. Any party found violating the embargo, whether it be a store selling the game, or even Josh or Kanpachi, can have their copies of the game confiscated under violation of an Informational Embargo, and can be charged with copyright infringement. No parties whether public or private currently have the right to disclose in-game information until this Saturday.
This is not copyright infringement.
