Eagle-eyed Pokemon fans caught something interesting in the debut trailer for Pokemon Brilliant Diamond and Pokemon Shining Pearl. At one point, the trailer shows an extra NPC in Floaroma Town. While this character wasn't in Diamond or Pearl, they were in Platinum, the third title in that series. This character gives you Gracidea if you have Shaymin in your collection. This character popping up in the trailer is pretty indisputable evidence that Brilliant Diamond and Shining Pearl will include at last some Platinum content.
