HKLUG appears to have obtained a copy of the LEGO Minifigure Character Encyclopedia and has shared images of the encyclopedia including the exclusive minifigure! Unfortunately, Mr.Gold is not the exclusive minifigure (this one has been rumored to be randomly distributed in Series 10 in very limited quantites). However, the book does come with an exclusive Toy Soldier collectable minifigure. Thanks to forum member legohunter for the news. (via Smashing Bricks)
*The book can now be pre-ordered from Amazon.com for $10.1 (reg.$18.99). Available May 1, 2013.
