Pokémon: Brilliant Diamond/Shining Pearl may only include Pokémon that appeared in the original game. This news comes from Nintendo France’s comment that only the previous four generations of Pokémon will be included in the upcoming re-enactment version, which means that we will not be included in Pokémon: Brilliant Diamond/Shining Pearl See the new Pokémon.
If this is true, then this is very different from the previous re-engraved version, because the previous re-engraved version of Pokémon will contain all the existing Pokémon. According to a comment found by NintendoSmash on Facebook, the translation of Nintendo’s official French account is: You can rediscover all Pokemon until the fourth generation. However, it is worth noting that the comment cannot be found on the page at this time, which indicates that it has been deleted.
On the contrary, an August article was roughly the same, except that the fourth generation was omitted. Either Nintendo wants to announce this disappointing news at a later date, or Nintendo’s French team has confused it. Of course, considering the infamous Date incident in Pokémon: Sword and Shield, this is not an unexpected move. This is the first time, not every Pokémon can become the main series of games, so this may be a way for the team to move forward.
