>>29092221...why? Honestly, given the continued persistence of earlier gens' monsters, subsequent generations introducing half as many as the first generation did seems about right. That'll add variety without completely pushing out the older designs. Hell, if Gen VI had had exactly 75 new Pokémon and included 15 Pokémon from each previous generation, that'd give you a total Pokédex of 150 that was still heavily skewed more recent designs.
