Due to Canada getting X and Y before anyone else info has been leaked. While we wait until X and Y are released The other gyms need talking about:
Viola is the first Gym and hers is the Bug Badge. She loses points for the lack of creativity in her badge name.
Grant is the second and is a Rock-Type Gym Leader who has the Bug Badge. Think of him as Brock 2.0.
Korrina is the fighting type Gym Leader is third and has the Rumble Badge. Trivia: Both Maylene and Korrina specialize in fighting types and both are the third gym leaders in their respective regions.
Ramos is fourth and his badge is the Plant badge. Trivia, both Ramos and Erika are specialists in Grass type pokemon and are the fourth gym leaders in ther respective regions.
Clemont is fifth and his badge is the Voltage Badge. Like Norman in Hoenn, Clemont won't challenge you until you have at least 4 badges.
Valerie is sixth and her badge is the Fairy Badge. Like Jasmine, Vallerie is the sixth gym leader in a new region to specialize in the newest Pokemon type.
Olympia is seventh and his/her badge is the Psychic badge. I'm not sure if Olympia is male or female. If female, good, if male, it's Tucker 2.0. Also like Tate and Liza of the Hoenn region, Olympia is the sevent gym leader of a region who specializes in Psychic types.
Wulfric is last and his badge is the Iceberg badge.
Now for Elite four. I'm not sure if they'll be like bw and you get to pick who you go up against first.
Wikstrom, master of Steel. His room will probably look the throne room of a castle made of metal.
Malva, mistress of fire. Her room is easy, the interior of an active volcano.
Drasna, mistress of dragon. Her room is dark and covered in dragon bones.
Siebold, master of water. His room, easy: an aquarium.
And the champ:
Diantha her room, big flashy with stars and spotlights.
That's my two cents on the matter what's your opinion?
