A link to some guys neogaf post isn't proof that he actually guessed the correct Pokemon game codename. So unless Gamefreak themselves came out and said that was their codename I see no reason to believe that he actually leaked anything. |
The Sun and Moon assets are registered as Niji by Nintendo, this isn't some random guess as the very material sent to the press by Nintendo had the name Niji.
