The Pokemon Company announced the Pokémon Brilliant Diamond and Shining Pearl remakes yesterday during the eventful Pokemon Direct presentation. It now looks like the contents of the third version, Pokémon Platinum, will appear in the Switch remakes. Twitter user Voltimer searched the debut preview for Pokemon Brilliant Diamond and Pokemon Shining Pearl and found the extra NPC that appears in the Platinum version of Floaroma Town. The character gives you Gracidea if you have Shaymin on hand. The confirmation of the Platinum content in the remakes has yet to be announced by The Pokemon Company.
