Here's a trailer, along with some screenshots for Ghost Trick that Capcom released yesterday. The video gives a good idea of what the gameplay and story of the DS game will be, as you see a swarthy gentlemen experiencing some car trouble at the hands of the player.
It reminds me an awful lot of Geist, a 2005 FPS for the Gamecube which failed pretty terribly. I rather liked the game but see much more promise in Ghost Trick simply because it's trying to do less. Not having to focus on combining first-person shooting mechanics in with your object and character manipulation puzzles ought to help out a lot.
Ghost Trick will release in North America January 2011.
