This seems to be a Bandai Namco thing. The first Digimon Cybersleuth game was delisted (from Playstation at least) a couple years back and only the sequel is available. I wonder if they think it'll funnel sales to the newer entries. For me it'd have the opposite effect.
Pretty ominous portent for an all digital future though either way.
