Like "The Avengers," this one promises a ton of extra footage, and while Ridley Scott may not be preparing a director's cut (a shock considering how many times he's done that to his earlier films), we should get a chance to sort through a dense selection of material that didn't make it into the theatrical feature, and we'll also get some pretty exhaustive behind-the-scenes material.  Ridley Scott is always well-treated by home video producer Charles de Lauzarika, and I'm sure this will be true of this film as well.  Besides, if any film this year will end up serving as a demo disc for sound and pictures, it's probably "Prometheus."
