Future Blu-ray Movies To Come With Playable Game Demos

Enthusiasts have long suggested the PlayStation 3 to their family and friends as one of the better and most affordable Blu-ray players. Lately, prices of Blu-ray players have been coming down, but the PS3 is still one of the better options out there. Sony is taking advantage of this by starting to offer game demos on their Blu-ray offerings. While these demos will only be playable on the PS3, they hope the extra value will help drive sales.
