Turns out that Japan will be getting a special edition of Gyakuten Saiban 4
, which is Phoenix Wright
4 to us English-speaking people. The special edition pack-in is an encyclopedia cartridge that reviews all of Phoenix's previous cases. It also contains all of the background music so you can listen at your leisure. Of course, our desire for such an extra is nonexistent as we haven't played any of the games beyond the first, but we have a feeling the Japanese will eat this up.
Check out Siliconera for some pictures of the encyclopedia in action.
