BBM added a page for the 2009 Rookie Edition set to their website today. The Rookie Edition set generally contains cards of the players drafted in the previous year's draft(s). (Oddly enough, even though the draft happened in 2008, it's referred to as the 2009 draft, or it least it will on the baseball cards). It's an 126 card, pack-based set with 95 cards for players who were drafted, 24 cards of active players (I'm betting that that's 2 per team), 2 cards for the new managers (Koji Akiyama of the Hawks and Akinobu Mayumi of the Tigers) and 5 cards that the Babel Fish translation is saying are "transfer interview card (The player who is transferred to this off new world)". I have no idea what that means.
The page on the website doesn't show any example cards. I hope that doesn't mean the cards are hideous. They couldn't be uglier than last year's cards, could they?
