Over the last couple weeks, BBM has announced this year's editions of the Carp, Giants and Marines team sets. The Carp set has 109 base cards (including apparently one for Kenta Maeda's no hitter on April 6), a nine card insert set (Soul Of CARP) and various autograph and jersey cards (looks like for Kenta Meada and Yuya Fukui, including cards with autographs or jerseys for both). The Giants set is a whopping 127 cards with (I think) two nine card insert sets (Young Giants and Super Metallic Giants) and memorabilia cards featuring up to four player's jerseys. The Marines set has 99 base cards, a nine card insert set (Counterattack Of Marines?) and memorabilia and autograph cards (the memorabilia cards have jerseys of Yoshihisa Naruse and Yuki Karakawa - one each by themselves and one with both).
There's no release date listed for the Carp set. The Marines set will be out in mid-May and the Giants set will be out in late-May.
In addition, BBM is releasing a box set to commemorate the Baystars being bought by DeNA. Called "Reborn", the set will contain 28 cards - 27 cards for players (and manager Kiyoshi Nakahata) and one "special" card. The "special" card will either be one of 12 "Newcomer 4 Hometown" insert cards or one of 10 possible memorabilia cards featuring jersey, bat or patch pieces from up to three players. The set will be released in mid-May.
