The annual Rookie Edition set from BBM came out last month, one of just a tiny handful to be released since the new year. Rookie Edition is by far the biggest release of the pre-season.
There are two parallels of the base set, a gold-foil signature version numbered to 75 and a red-foil signature version numbered to 30. BBM announced 80 or 81 of the players appear in the parallel sets. BBM doesn't mention it on their site but it appears there is also a blue foil signature version numbered to the player's assigned jersey number.
NPB Card Guy has a post on this set too.
