Joystiq has some interesting information about Wii Music and the Wii Health Pack:

  • Wii-remote-as-conductor’s-baton control shown at the demo
  • take control of specific musicians
  • send saved compositions to other Wii users
  • the game will collect biometric data and send it to local hospitals (contracted by Nintendo) through a Wii channel
  • this data will be processed by the hospital and sent back as a home check up a few hours later

Sounds like these could be really cool if they’re executed right.
