all rumors are going to be confirmed at this point:
Fairy will be SE Dark, and Fighting as well as Dragon...Fairy will be IMMUNE to Dragon, and Fire & Psychic typed are Not Very Effected by Fairy.
Fennekin evo will be Fire/Psychic, Chespin evo will be Grass/Dark and Froakie will be Water/Fighting.
Mewtwo will have TWO new formes, and are activated by items.
Dual-type attacks (Scald might be BOTH Water/Fire)
A Psychic-type Pokemon named Espurr (ESP + purr) evolves into Meowstick (Meow + mystic?). (Sounds like Psychic-type cats. Meowstick's name sounds too similar to Meowth to me though.)
Another professor named Sycamore gives you either Bulbasaur, Charmander, or Squirtle.
A new move, Belch, is a Poison-type attack that has a base power of 120. The user must consume a held Berry to perform it.
