The set is 96 cards, which off hand I think is the smallest number of cards in this set ever. 83 of the cards feature players taken in last October's draft, including the afore-mentioned Ohtani, Sugano and Fujinami.
The draft pick cards are pretty much like all the other draft pick cards in the previous Rookie Edition set - posed shots of the players holding balls or bats, making "guts" poses or faking a pitching motion. I think the poses are a little more vanilla this year than most - no one doing the splits, no one playing "air violin", everyone in their team's uniform rather than a suit. About the only oddity in the set is that because Ohtani and the Fighters have been toying with the idea of him being a two-way player, BBM included two cards of Ohtani - one with him "pitching" and one with him holding a bat. Both cards have the same number (#42) but it appears that both are treated as equal parts of the set - the set contains 96 cards that are numbered 1-95 with an extra card 42.
Here's some example cards:
There's a one card checklist listing all of the draft pick cards (although only listing one card for Ohtani). Unlike previous years, the card doesn't show any pictures of the players - it's just a straight checklist card.
The checklist card does not list the 12 card "Then And Now" subset for the set. Each card in this subset features one draftee from each team (it's the number one pick for each team except the Marines - it's third rounder Tatsuhiro Tamura for them) along with a vintage picture of some other player. Trying to figure out the connection between the draftee and the other player has frankly been the most interesting thing about this set. Sugano is paired with Tatsunori Hara, his uncle as well as his manager with the Giants). Koji Fukutani of the Dragons is shown with Shoze Etoh, a former Dragon as well as Fukutani's coach when he was at Keio University. Hiroyuki Shirasaki of the Baystars and Tamura of the Marines are paired with their managers - Kiyoshi Nakahata and Tsutomu Itoh respectively. Bizarrely, Fujinami shares his card with Tsuyoshi Nishioka, pictured from his press conference announcing his signing with the Tigers. I have not figured out the connections on the other cards - Taichi Ishikawa and Tatsuji Nishimura, Swallows; Hiroki Takahashi and Sachio Kinugasa, Carp; Ohtani and Mitsuo Yoshikawa, Fighters; Tatsushi Masuda and Shigekazu Mori, Lions; Nao Higashihama and Kenichi Watatabe, Hawks; Yudai Mori and Masahiro Tanaka, Eagles and Takahiro Matsuba and Hiroshi Kobayashi, Buffaloes (Kobayashi is actually shown as a member of the Orix Blue Wave). Here's a couple sample cards:
