Ok, sorry. Some parts of the trailer mite have been real gameplay or on par with real gameplay (like when the boy runs up to the monster in the beginning*, that part didnt look so advanced) but most parts, for example the most impressive parts where the monster stumbles over a cliff, and when they dive, and when they both lie in the grass by that stone wall - those parts are cleary 'cut-scene' graphics.
EDIT: * I don't mean the beginning where the boy is running and where the viewer thinks the boy is being chased by the rat monster - because that's also a typical cut-scene, but a lil later when he sneaks or walks to the lieing monster inside the cave, u see that short scene from pretty much just one angle - that scene could well be 'in-game'.
