On May 2, Nintendo filed a trademark for the name 'Delta Emerald' in Japan, but it was only today that the filing was made public. With the name Delta Emerald falling into Nintendo's hands, it could be that a remake of Pokémon Emerald will follow closely behind Pokémon Omega Ruby and Alpha Sapphire.
It was just earlier this month when Nintendo announced the remakes of Pokémon Ruby and Sapphire for the Nintendo 3DS. Few details were given other than a trailer briefly showing off the 3D models of Groudon and Kyogre.
While few announcements have been made by Nintendo concerning the Honen remakes, Pokémon Omega Ruby and Alpha Sapphire will release on the Nintendo 3DS this November.
