I saw two during Lost. One had no game imagery AT ALL, can't even remember what it was for! It was very short too, kind of like they can't be bothered advertising as they know they've created a false shortage.
The other advert was for Perfect Dark Zero, which mixed footage and reality (20% in game?), and was a bit longer but made no sense. The shots that were shown actually looked pretty poor - a couple of nice effects, but the surroundings looked like poor quality textures. "Does it show it's N64 heritage *that* much?" were my thoughts...not "must get it now"...
