As of December 2007, the Wii will be replacing MP3 compatibility with the capability to play AAC files which Nintendo state offers greater sound quality than MP3 files at the same size. The new compatibility of files will work with the .m4a format too and you can select to shuffle songs.

*Wii consoles sold in retail stores starting in December 2007 should include AAC file support.

*For Wii Console owners without the AAC file compatibility, you can download the updated version of the Photo Channel from the Wii Shop Channel starting in early December 2007. Please note that once you download the updated Photo Channel (ver 1.1), you will no longer be able to play MP3 format music files.

Additionally, consumers who purchase a Wii console with the updated Photo Channel (ver. 1.1) already installed will not be able to install the previous version to support MP3 playback.
