This week, Calbee's website announced that this year's third series will be released on October 3. There are 72 "regular" cards in the set (6 per team) along with a couple insert/sub sets. There's a 25 card All Star set featuring players from the All Star Series including the MVPs of each game. There are four checklist cards and 24 Star cards (both numbered as continuations of the respective sets in the earlier series).
If you're thinking that this year's Calbee set seems smaller than last year's, you are correct. The total count of "regular" cards this year is 228, 60 fewer than last year. The number of subsets and insert sets is smaller this year also. I don't know if this is related to the earthquake or the economy, but BBM's 1st Version set is much smaller this year as well, so whatever the issue is, it may not be isolated to Calbee.
Speaking of BBM, AmiAmi and Discount Niki are listing two new sets - a box set called "Our Friends" or "Friends Of The Ballpark Fun" featuring team mascots both past and present and a pack-based set featuring the cheerleader/dance teams for each team.
