Happened to check Calbee's website today and discovered that they have information out about this year's Series 1 cards. As always, they've put a checklist on line for the set as well. The set will have 72 "regular" cards (6 per team, down from 8 last year) as well as a couple of insert/subsets. There's a two card League Champion (LC) subset featuring the Hawks and the Dragons, last year's 1st place finishers (although only one of them made it to the Nippon Series). There's a three card Nippon Series (NS) subset and four checklist cards. There's also a 24 card Top Player (TP) subset featuring two players from each team. There's a 22 card subset labeled "T" that I think is for 2010 award winners and statistical leaders. And finally, there's a 12 card subset (1 card per team) labeled "D" that I think is for rookies - because the Fighters' card is for - you guessed it - Yuki Saitoh.
The set will be out on March 21.
