How many sets are they planning to make for Kingdom Hearts?

This is a tough question to answer really. It all depends on how well the game sells and from what I've heard around town, the game IS selling, there just isn't a whole lot of the players on the boards as of yet.

Back to your question though, I believe they'll at least print all of the japanese cards...at least I hope so anyway...this will consist of probably 3 or so more sets here in America. After that, who knows what they'll do with it, but what I've ALWAYS said since this question was first posed...why would a company buy the rights to a game they knew was going to die?
