OK, apparently the 1977 set was such a success for the All Japan Baseball Foundation that they and Epoch are releasing a similar set for 1987. 1987 was the year that Sachio Kinugasa broke Lou Gehrig's consecutive game streak as well as the final year for Tokyo's Korakuen Stadium so I would expect cards for those events as well as others.
The set is a box set containing 60 cards - 59 "regular" cards plus one memorabilia or parallel card. The 59 "regular" cards breaks down to 48 player cards, 10 cards for events of 1987 and a checklist card. The 48 player cards might include cards for the managers of the Nippon Series teams - the Giants (Sadaharu Oh) and the Lions manager (Masahiko Mori). I think that the set was scheduled to be released in late March but I don't know if it came out on schedule.
