On their website this week, BBM announced the first of the 2010 team sets - the Swallows and the Eagles.
The Swallows set will have 99 "regular" cards - 75 cards for the players, coaches and manager, 4 cards for a "Uniform Number 1" subset, a checklist card, one card that I have no idea what it is, a nine card puzzle subset, a three card "Closeup" subset and six cards for the BBM 20th Anniversary cross-set subset. There's a 7 card "League Leader" insert set and the usual memorabilia and autograph insert cards. There will also be parallel sets for the player, coaches and manager cards and the "League Leader" inserts.
I think the "Uniform Number 1" subset has something to do with Norichika Aoka changing his uniform number from 23 to 1. The subset probably shows other players who've worn number 1 for the Swallows, like Takahiro Ikeyama, Tsutomu Wakamatsu and Akinori Iwamura.
The Eagles will also have 99 "regular" cards - 72 cards of the players and manager, 1 checklist card, 4 cards of "promising young players", 4 cards for players who reached career highs in 2009, a nine card puzzle subset, a three card "New Force" subset and six cards for the BBM 20th Anniversary cross-set subset. There's a nine card "Leading Players" insert set and some autographed insert cards.
Both sets will be released at the end of March.
