this is just the gameplay trailer slowed down. Game-informer has already done this.
No there is more to it then that, almost every clip has different placement, some are flipped, deleted, shaded, reversed ect. There is not much you can do with a re-edit, however the way it is now has shown me things I did not notice in the original. IGN has a similar video to the game informer one also there are now quite a few on youtube.
Edit: wait is there a Game Informer video anolysis?
