Nintendo has announced its demo disc in the US will feature five playable demos. The disc will be released on the 25th of May and will contain demos of the following games:

Splinter Cell
Viewtiful Joe
Billy Hatcher and the Giant Egg
Sonic Adventure DX
Soul Calibur II

The disc may contain more playable demos, and will probably also feature some video previews.

This new marketing tactic will definetely help the growing number of people that recently purchased a GameCube in the States discover new games, thanks to the "Console and free game bundle" for only $149.95. The games available in this offer so far are: The Legend of Zelda: The Wind Waker, Metroid Prime, Star Fox Adventures, or Mario Party 4.
