The first release will be the first movie in the series, Mewtwo Strikes Back, released over here as Pokémon: The First Movie. It will be released as a download for just 500 yen. Strangely, the rest of the releases -- four more movies -- won't be released as downloads (at least, they aren't planned to be for now), but as MicroSD cards preloaded with one movie each for 2,980 yen ($27) Lucario and the Mystery of Mew will be released as a special-edition package containing a DSVision card for 4,280 yen ($39).
This actually isn't AM3's first experiment in selling Pokémon video for play on Nintendo handhelds. The DSVision creator previously sold Pokémon movies on SD cards for play on their Advance Movie Adaptor.
