A free update to the Japanese version of Pokédex 3D (Pokémon 3D Zukan BW ポケモン立体図鑑BW) has just been made available. The update allows players to download every single Pokémon normally via Spotpass, including all the Pokémon that previously needed their AR marker scanned before they could be downloaded, and all the Pokémon that had to be traded from other players. It also unlocks the Pokémon Victini, Cobalon, Terrakion, Virizion, Reshiram and Zekrom, which were previously unlocked by scanning their special AR markers. The update does not add any Pokémon from the previous generations or the new formes revealed for Black 2 White 2, however these will be available in Pokémon National Zukan Pro (ポケモン全国図鑑Pro), which will be released July 14th, 2012 for 1500 yen.
