This video features the developers discussing the difference between last gen and the current gen. They've confirmed that for certain parts of the game the touch pad will be usable and the game will also use player interface. This game features full particle effects and physics unlike last gen (which means I must destroy all). lastly they a small bit of the premise of the story and our part to play in it. Can't wait!
