The official Pokémon website has also confirmed that outside of Japan the new forms of Groudon and Kyogre are known as Primal Groudon and Primal Kyogre. The two forms are obtained through Primal Reversion. We've also got a pretty new map of the Hoenn region which you can see above.
The official release dates for the two games have been confirmed. Pokémon Omega Ruby and Pokémon Alpha Sapphire will be released for the 3DS in the US, Japan and Australia on the 21st of November. The games will then be released in Europe on the 28th.
