iPod Mini Software Update?

According to Think Secret, Apple is set to pull the wraps off of a software update for the iPod Mini which would provide the same functionality as the current big brother click-wheel iPod. The update should include the single-click shuffle function, variable-rate audiobook playback, multiple editable on-the-go playlists, and interface sounds through the headphones. A release date apparently hasn't been set yet, but may appear as early as today.
