Yes, the Kingdom Hearts 3D AR Cards will be available from tomorrow through Club Nintendo and will cost 200 Stars. These will be different from the two cards that come with the game.
As many of you will already know, holding these AR Cards up to the Nintendo 3DS cameras will allow you to immediately recruit a new Spirit to your party in Kingdom Hearts 3D, one of the best 3DS games.
The same three cards appear in each pack so you don't need to purchase more than one pack. The pack features a Club Nintendo logo on the wrapping paper.
