Recently revealed were the 3DS remakes for Pokémon Ruby and Sapphire, Pokémon Omega Ruby and Alpha Sapphire. These games are planned for release in November 2014. Like Pokémon X and Y, these games will be released worldwide simultaneously.
A trailer has been released at Pokemon.com revealing the boxart and approximate release date. The cover Pokemon are Groudon and Kyogre, as expected. Though they do look slightly different...Mega Evolutions, perhaps?
