This is New Pokemon information that it set to be released the following week, specifically what will be shared with fans via the Official Pokemon X/Y website. and in Press Releases sent out. Although they may divulge additional information, I believe this is also what CoroCoro and the E3 Round Table will cover.

- Two New Types: Fairy-type and Echo-type. Japanese names apparently (Fairy) [フェアリータイプ] and (Hibiki) [ひびきタイプ]. Represented by light-pink and dark gray respectively.
- Fairy-type is weak to Poison and strong against Dark. Cleffa, Clefairy, and Clefable are now Fairy.
- Echo-type is immune to itself and strong against Ghost. Whismur, Loudred, and Exploud are now Echo.
- Xerneas is pure-Fairy. "Rebirth Pokemon". Horns are able to read the brainwaves of living creatures, storing the memory and knowledge of the planet.
- Yveltal is Echo/Flying. "Reverse Pokemon". Its wing-beat resonates with every living creature's heart, stirring them into action and their will to live.
- Sylveon is pure-Fairy, Harmony Pokemon. Able to befriend any Pokemon using its soothing ribbons. Ability "Heart Dust" slightly heals teammates when it is switched out with them. Signature move is "Symphony Beam", very powerful but weakens when teammates are fainted.
- Mewtwo has two Formes. One we've seen is "Réveil Forme", Psychic/Echo, vibrates its body at high frequencies to move at super speed. Transforms via the "Awakened Gene", found in the X Version.
- Second one is "Sommeil Forme". Smaller, and asleep with a weird pink "egg" growing from its brain. Psychic/Fairy, sleeps while absorbing energy to heighten its brain power. Transforms via the "Dormant Gene", found in the Y Version.
