Fans from all around the world are eager for November 21, the day when Nintendo will release the two games in the 6th generation of Pokemon for Nintendo 3DS.

A Japanese magazine Coro Coro has already revealed four brand new Mega Pokémon. Mega Pidgeot, Mega Beedrill, Mega Latias and Mega Latios will be the biggest attraction of Ruby and Sapphire edition remakes this Fall.

The idea of mega Evolution that was implemented in Pokémon X and Y will be a prominent feature for the upcoming games. While Mega Pidgeot and Mega Beedrill will be available for both versions, Mega Latias will be exclusive for Alpha Sapphire and Mega Latios will be available in Omega Ruby only.

To obtain these new legendary Pokémon, players will require a serial code that will be distributed to obtain the EON Ticket.

In addition, Nintendo has announced that the demo version of Omega Ruby and Alpha Sapphire versions will be available for download at the Nintendo eShop from October 15. The Serial Code for legendary Pokémon will be required for downloading the demo, and will be distributed in various gaming events and published in gaming magazines.

"The new titles promise to take players through a dramatic story within a spectacular new world," Serebii reports, "Despite being a remake, this game introduces numerous new aspects including brand new Mega Evolutions, which weren't in Pokémon X & Y, as well as an entirely new concept based upon the legendary Pokémon Groudon &K yogre known as Primal Reversion."

While Alpha Sapphire will feature Team Aqua in the story line, Team Magma will be appearing in Omega Ruby version, keeping the two story line slightly different from each other.
