When Nintendo releases Pokémon Black and White on March 6th it will likely be one of the biggest sellers of the year. Its release in Japan sold an astounding 2.55 million copies in the first week alone. So, it's no wonder that this record-breaking franchise is featured in this year's Guinness World Records 2011 Gamer's Edition now available in paperback and eBook.
