I was kind of surprised to discover that despite having many more players represented in their set than Topps did in all of theirs, Topps actually had cards of guys who didn't make it into the Konami set. Some of that was because Konami apparently made a decision to only show cards of people who actually played in the Classic, so for example, Alex Rodriguez doesn't appear in the set while he had at least three cards in the Topps sets. (In fairness to Topps, a couple of their sets were released prior to the Classic starting so it was unclear who was actually going to make the teams.) Another guy who doesn't show up in Konami's set was Dustin Pedroia, who got injured during the Classic and was replaced by Brian Roberts (who is in the set). But there's a bunch of guys like Yadier Molina, Carlos Lee and Pedro Martinez that for whatever reason don't appear in Konami's set.
Here's some example cards. The pictures are pretty much all action shots taken during the Classic:
Konami is a sponsor for the 2013 World Baseball Classic, so I suspect that they will be doing another card set this year.
