Nintendo confirmed that Pokemon X & Y will include new Mega Evolution and Super Training. Mega Evolution requires Mega Stones, which can be obtained throughout the Kalos region, when you use the mega stone on specific Pokemons, they can evolve into the Mega form which unleashes their hidden strength and power. Mega evolution will only appear in battles, the Pokemon will return to its normal form after battles. There are several types of Mega Stones, such as Lucarionite for Lucario and Blazikenite for Torchic. Some other Pokemons capable of mega evolve include Mewtwo, Blaziken, Absol, Ampharos and Mawile.
Super Training allows players to train their Pokemons while they are not in battle, and increase their base stats like HP, Attack, Defense, Sp. Attack, etc. The training sessions are mini games like shooting balloons and dodge shots from the balloon bots.
Three new Pokemons have been revealed, include Dedenne (electric/fairy); Bunnelby (normal) and Skiddo (grass), a pre-evolved form of Gogoat.
