For video games, discs are here to stay

Music and movie downloads are pushing the entertainment industry online, but don’t expect video game discs to go the way of the CD any time soon.

For many big video game companies, not to mention consumers, extra online content is helping enhance games sold on discs. For "Grand Theft Auto IV," considered by many to be the year’s most-anticipated console game, this means extra episodes available for download exclusively through Microsoft Corp.’s Xbox 360.

Gamers who have been holding out to buy a next-generation console until a worthy game like the latest GTA hits shelves will likely flock to the 360 over Sony Corp.’s PlayStation 3, which will not offer any extra episodic content.
