Well Srg,

there's a guy who is supposedly giving out Generation 6 information, and ALL of his predictions have been true, some being 3 months before release.
 * Fairy will be a new type. It is weak to Poison and Steel, immune to Dragon, super effective against Dragon, Dark, and Fighting, and Fire and Psychic-type Pokemon take half damage from it.
 * Sylveon is Fairy-type. Some older Pokemon will be reclassified to Fairy, such as Mawile (Steel/Fairy).
 * "super effective against Dragon, Dark and Fighting" contrasts this.
