Level-5 announced a new Nintendo 3DS Professor Layton game this morning for Japan on Nintendo's Direct video feed. CEO Akihiro Hino introduced the game and teased a bit of in-game footage – spoilers: it looks like Professor Layton! – he also noted that this will be Layton's "last adventure." That doesn't necessarily mean the end of Layton, of course, just that the game's main character is on his way out.
