Well here's something new. On December 29th, Sony will release the hit sci-fi film District 9 on Blu-ray, and are adding a unique bonus feature: a playable demo of the PlayStation 3 game God Of War III, due in 2010. According to Sony's press release, "after successfully completing the game demo, the consumer will be able to unlock an exclusive making-of featurette about the game." (And what's at the top of the sphere? An information desk!) Sony is touting this as "the first movie/game demo hybrid Blu-ray in the US." And a pretty smart pairing of movie and game, too.
