Odd as it may seem, Digital Leisure has released the laserdisc classic arcade game Dragon's Lair on Blu-ray. They put it out on HD DVD some time ago, but are just now coming around to Blu-ray. It's apparently a BD-J, or Blu-ray Disc Java, which is the way they get interactive content on Blu-ray, but still playable on DVD players. They say it's got lots of 'exciting special features'.
The official site doesn't have a site for the BD-J yet, but the game is 'coming soon,' according to the postard they sent out.
