As part of an update available next month, the Wii Photo Channel will be replacing the MP3 file format with the ability to play higher-quality AAC files. Also compatible will be MP4 audio files in the m4a format, but MP3 is about to be kicked to the curb. So much for most of my music library.
Current Wii owners should be able to simply skip the update if they wish to keep their MP3s, but all consoles sold at retail next month and beyond will come with it already installed. Additionally, the new Photo Channel version 1.1 will allow you to shuffle songs for random playback and set any picture you like as the Photo Channel icon in the Wii menu, but what good is any of that when you just finished explaining to Grandma what an MP3 is? She's going to be so confused now.
