Generation VI is the first generation of the Pokémon series to be exclusively 3D, meaning it is the first video games ever that have to require a Nintendo 3DS system. Not very much else is known about it except that the first set of games are known as Pokémon X and Y version. They are set to release worldwide in October of 2013.
The generation features many changes such as the games's 3D cell shaped graphics, more indepth battle scenes and a brand new camera view. The name of the new region is not known yet but the region probably draw inspiration from the continent of Europe, as proven the Eiffel Tower which is the main monument of the city of Paris, France. Also, a bridge that has been based on the popular London Bridge has also been appeared in the game as seen in the trailer after that shows the female player is running over it.
The only known new Pokémon are the starters Chespin (Grass), Fennekin (Fire), and Froakie (Water). Two possible mascots have been shown and their names are Xerneas (Exclusive mascot to Pokemon X Version), and Yveltal (Exclusive mascot to Pokemon Y Version). And the new evolution of Eevee, Ninfia has also recently been introduced. However there has been no further information given yet on it's type or on the method used to get Eevee to evolve into it.
