Pokémon Omega Ruby
A huge collection of screens, a new trailer, and new details (including an upcoming demo) have all been revealed for Pokémon Omega Ruby and Alpha Sapphire.
Along with the reveal that Rayquaza will join legendary Pokémon (Pokémen?) Groudon and Kyogre in the game, more Mega Evolved Pokémon have been showcased. Also revealed are some new abilities for the legendary Pokémon. Groudon has the Desolate Land ability while Kyogre has Primordial Sea. The abilities prevent weather changing abilities from working from opponents and also eliminate the effectiveness of certain elemental attacks.
Among the new details is the confirmation that the Pokémon Bank and Pokémon Global Link will be compatible with the new games, and that a special demo is planned for the game. No details about when or how the demo will be acquired were offered, but Pokémon found in the demo will apparently transfer over to the main games when they release November 21 for 3DS. The Pokeemon Company promises more details about how to access the demo will be revealed soon.
