Predictions for Gen VI
Starters: all dual types throughout evolutions. Grass/Dragon-type reptile-based Pokémon (perfect choice), Fire/Fighting-type dog-based Pokémon (Not Flareon, please), Water/Flying-type flying-squirrel-based Pokémon (Emolga looks good, but I don't want to see many electric squirrels (including flying squirrels)).
Number of new Pokémon: over 100 plus new cross-gen evos and pre-evos.
Other: More Move Tutors, all new Trainers for Gen VI including RSE remakes. Revised Egg Grouping systems.
