Sony's Puppeteer seems to be coming along pretty nicely, and on September 10th of this year, we'll be able to see the finished product. At a demonstration at GDC, Sony confirmed to Joystiq that the game will indeed see a September release, and will launch at retail and on the PSN for the PlayStation 3.
What really intrigues me is the concept of the entire game taking place on one giant theatrical stage. It's basically what Black Knight Sword tried to do, but a little cooler. The LittleBigPlanet style visuals also help draw me in!
