Each Pokémon in Pokémon X/Y will have a separate Pokédex entry for every language, only attainable by trading with other regions

Not only will the upcoming Pokémon X/Y have the largest swath of pokémon to catch in series history, but each one of those pokémon will have multiple “version”, one for each language that the game is available in. Players’ Pokédex will keep track of these entries, so when you trade an American Pikachu for a Japanese Pikachu, your ‘dex will allow you to view both the English and the Japanese versions of the pokémon’s Pokédex entry.

What does this mean for completionists? Well, Game Freak has effectively more-than-tripled the amount of work you’ll need to do in order to get a full Pokédex, which is both a little bit evil and a little bit funny.
