Pokemon: Black and White hasn’t released in Japan yet, but the game is already a success. That’s because over one million people have pre-ordered the game, which is the fastest ever for a DS game.

The last main release in the series, Pokemon: Diamond and Pearl, sold three million copies within its first two days on sale in Japan. Pokemon: Black and White, meanwhile, is set to have 1.5 million pre-orders by the time it releases in September.
