But from what I remember, that merchandise only hinted at those Pokemon appearing in the anime, not specifically that Satoshi would get them. Blacky's merchandise being used as "evidence" of Satoshi possibly capturing one is especially amusing to me because Blacky and its entire evolutionary line seem to get new merchandise every other month anyway because of their popularity, so it seems like a non-factor.
