Here's the TGS trailer for
The Last Guardian which features some commentary by the developer on some of the inspiration behind the game as well as a little bit of new footage (starting at the 3:00 mark). While they are still tight lipped on the plot of the game and what the actual game mechanics are (they do talk about hanging onto the tail of the creature) I'm still drawn to the game at some base emotional level. I know I'm a sap but the game elicits some of the same feelings of pet ownership in me. Given the pedigree of the developers this is probably a game to keep an eye on.
