Older Zunes are getting some new software love too with a 3.2 update. The new software is fully Windows 7 compliant, naturally. It Supports all those nifty 7 features like Jump Lists, previews, and Aero Snap.

Other new features of the software include a Quickplay menu to access your favorite media on the Zune HD player. Smart DJ is rather like the Apple Genius feature and creates music mixes with similar genres from your collection and it will add music from the Zune marketplace for those with a Zune Pass.

A new Mini Player mode is now available that keeps the mini player on top of any PC apps that are running. Microsoft has also introduced download to rent or own movies and TV shows in SD and HD formats. Engadget also reports that the ability to move DRM tracks between Zune users has been removed from the new software.

Perhaps the most interesting new tidbit of info for the new Zune HD player is that Microsoft plans to position the device as a mobile gaming platform. If the popularity of gaming on the iPod touch and iPhone are an indication of the popularity of mobile gaming, this is a very good thing.

The official Microsoft press release states, "Later this year, Zune plans to release free applications such as Twitter for Zune and Facebook for Zune, in addition to fun 3-D games such as "Project Gotham Racing: Ferrari Edition," "Vans Sk8: Pool Service" and "Audiosurf(TM) Tilt." Games can be added to Zune HD via Zune Marketplace over the Wi-Fi connection or when connected to the Zune PC software."

Microsoft reports that its strategy at this point is to keep some games and apps offered on the Zune HD as free products that are developed in-house or in close collaboration with third parties. Premium 3D games will be items you have to purchase presumably. There will be no SDK to allow devs to build apps for the Zune HD at this point.

The launch of the Zune HD today also marks the retirement of all other Zune devices.
