The promotional video and leaked shots already made it clear but now it's official: the Zune HD will be a gaming and application platform. In
addition to a few casual games, calculator and MSN Weather apps pre-loaded onto the Zune HD, the official Microsoft press release touting the launch contains this little nugget of gaming gold:

"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."

Hear that Nintendo, Sony, and Apple? There's a new handheld gaming platform in town. All that remains to be seen is how it will integrate with the Xbox 360.
