Castrum - Professor Layton and the Last Specter, slated for release October 17th on the DS, also comes with a bonus RPG, Professor Layton's London Life, which unlike the original Japanese release does not need to be unlocked.
In addition to this, a new Tetris game is coming to the 3DS on October 7th, called Tetris: Axis (swastika tetris anyone?), which features the usual accoutrements of multiplayer, gimmick functionality and what-not.
