Wii owners can download the new Netflix disc-free streaming update from the Wii Shop Channel.  Up until now, Netflix viewing through the Wii needed a special Netflix disc.  This update adds Netflix as a menu option on the Wii Menu.  Previously, the only console which had disk free streaming of Netflix was the XBox 360. 

Sony’s Playstation 3 also requires a disk, but an update is expected to be released sometime today to allow disk free streaming.

You still need a Netflix subscription in order to take advantage of the streaming.  Subscriptions start at $8.99 a month.
