The Zune may be set for its first true feature update in less than two weeks, according to the schedule for the presenters at the music-oriented Digital NARM expo. Microsoft's music marketing director Christina Calio is set to deliver a presentation at 5PM May 1st that will feature "exciting updates on developments in Microsoft's new innovative device," according to the show notes. Though the listing expectedly avoids details, the speech is the first to openly suggest new features for the Zune, which has remained largely static since its November introduction.

Microsoft has already hinted at flash-based players and enhaned software, such as better handling of podcasts, but has yet to commit to a specific launch window outside of the 2007 holiday season for any of its new devices.

The greatest change to date has been the release of a limited edition pink 30GB model last week. [via ClicZune]
