This is a pretty cool post I found on My Nintendo News.
|Released||Title||March 2012||March 2013||Increase|
|2007||Pokémon Diamond/Pearl||17.61 million||17.63 million||+20,000|
|2010||Pokémon HeartGold/SoulSilver||12.40 million||12.67 million||+270,000|
|2011||Pokémon Black/White||14.71 million||15.42 million||+710,000|
Last year, Nintendo released the latest Game Freak-developed Pokémon role-playing games for the Nintendo DS, Pokémon Black 2 and Pokémon White 2 – both of which have sold over seven million units. As you can see in the above table, which was compiled from Nintendo’s various financial reports over the last year, older Pokémon games for the Nintendo DS are still selling well, especially considering all of them were released over two years ago. The next installments in the main Pokémon series, Pokémon X and Pokémon Y, are scheduled to release later this year, exclusively for the Nintendo 3DS.
