The two latest additions to the neverending Pokémon franchise managed to move an incredible 2.6 million units during their first two days on Japanese store shelves -- but how have Black and White fared since then? Unsurprisingly, they've done just fine; according to sales statistics from Enterbrain, this week saw the pair's combined sales reach 5,036,724 units.

Pokémon Black and White aren't the first games to reach this impressive mark -- in fact, four other DS games have managed to reach five million sales in the past. However, no other DS title has managed to reach five million quite as quickly as Black and White, which have only been available for 17 weeks. We guess that just goes to prove that, for some people "Gotta Catch 'Em All" isn't just a catchphrase, it's a way of life.
